For Slashdot's 15th Anniversary in October we had a contest with user-submitted logos each day. These are the winners selected by day.
1From Australia, and from Ben Minerds -- a guy with "nerds" right in his name
2Artist Jason Jacques says: 'While the main text itself is "obvious", in its fully animated form this logo provides additional challenge in that the remainder of the message must be decoded. Can you figure it out? If so, mail answer to How did he do it? After calculating the necessary sizes and bit patterns on paper, the static image of the entire message was generated using Pixlemator on Mac OS X (Lion). This image was then processed using ImageMagick (and a short shell script) using Ubuntu. Additional editing was done to the logo portion in Pixelmator (OS X). These frames were then assembled into an animated gif using Jasc Animation Shop on Windows XP. Finally, the images were optimized to minimise their size using ImageOptim, back on OS X.'
3Artist Chuck Han, aka UnanimousCoward, used screen capture and The GIMP.
4Avrum Cohen ("sleepypsycho" on Slashdot) wants to remind you of something that happened on this day in 1957 which probably in a roundabout way led to the site you're reading now. He used the excellent open source, Free Software vector art program Inkscape to create it
5October 5th 1864 was the birth date of Louis Lumiere, who made the first motion picture in 1895 -- and invented camera and projection equipment for making and viewing it. So don't give Edison all the credit, though you can always join the dispute about cinematic primacy (see Reader Ed Menjes created this image with The GIMP.
6On October 6, 1990, the space shuttle Discovery lifted off with the solar probe Ulysses aboard -- a probe which operated for nearly 19 years, thanks to a series of mission extensions made possible by dedicated engineers and programmers. Check out the story at Wikipedia: From an artist who'd rather remain anonymous, this image of Shuttle and Earth was made in GIMP.
7Reader Jack Thompson supplies this spare take on the Slashdot logo (created in Adobe Photoshop CS6), which also serves as a reading comprehension test.
8Reader Itay Chamiel (UID phozz bare) supplies today's logo, illustrating what "Slashdot" looks through the filter of "an Atari 8-bit computer in Graphics Mode 2 and some real-time register changes that cause each scanline to show a different color cycling through all 128 colors that the Atari can normally display." Itay's drawing tools and process included an Altirra emulator, some BASIC and 6502 assembly, Virtualdub, FFmpeg, and GIMP.
9This takes dedication: Reader Andreas Owen writes of today's logo: "I used mspaint and made the drawing pixel by pixel >_<"
10Another from Avrum Cohen, this time with feeling: Each bot is programmed with simple movement instruction, and moves in a random direction for a random interval within a specified range, then adjusts its direction. If a bot contacts a point along the center line of a letter (or one of a few addition seed point) the bot halts. If a bot comes in contact with a halted bot and the moving bot is within the border of a slashdot letter it halts. Bots bounce off the boundary area of the logo. Source locations for letters are not depicted in displayed image
11Note: for the right cadence, follow along with the old counting song from Sesame Street ( Joseph DeVincentis's logo was created using Emacs to create SVG files of the frames; Inkscape to convert those into bitmaps; Xv to convert those to GIFs; and Gifsicle to create an animated GIF and add transparency. He used the free DejaVu Serif font, "though each character is positioned separately, and the slash is differently sized because the one from the font ran below the baseline a bit, which I didn't want."
12Says reader Nick: "A quote from Dennis: 'I'm not a person who particularly had heros when growing up.' Well, he was certainly a hero to a lot of *us* when growing up."
13For Super Mario maximum nostalgia mode (to reach it, you just keep hitting "A" until your thumb hurts and you're crying), Hans Baas made today's GIMP on Xubuntu with the Pet Me 64 font.
14Reader Heiko Selber writes of his entry: 'The font comes from the Windows 7 CMD window, the animation was done using the GIMP (duplicate layer, move left by 5 pixels, repeat ad nauseam => RSI?).'
15Teddy Gutan has squeezed in for today confetti, a party hat, and more color than our workaday logo; day 15 gets number 15, too.
16Do not touch your screen. But Florian Kunze's take on the Slashdot logo is written in Braille (using freeware font Braille.ttf), so if you have a 3-D printer you could read it in the dark. One source, if you also want to use this font:
17Artist Piotr Dabrowski lets this one speak for itself.
18Sean Murphy drags us all to Middle Earth with this version of Slashdot, as it might be written in Elvish. He writes: "The font used is based on Tengwar Annatar, a typeface created by J.R.R. Tolkien to depict the Elvish writing of Middle-Earth. I've altered it to resemble hand-written Elvish, rather than the usual 'machine-generated' Elvish characters you usually see. Perhaps this is a note from an Elvish warrior, dying valiantly on a battlefield, to his lost love: 'SLASHDOT!'" Perhaps!
19Sanmitra Kale says "The Turtle was force fed to me in school and I hated my first brush with programming. Now I think it is the only language that makes ANY sense at all. PS: I Googled and found that a Slashdot story this year informed that Baskerville is the greatest font who ever lived so I used that font.)" Sanmitra used a notebook, a red Banner pen, MSWLogo, MS Paint, and Adobe PS CS5.
20Øyvind Søvøy writes of today's logo: "This is a stylised version of the Slashdot logo, followed by the number 15 in binary behind it, lovingly crafted (and of course handmade, using my mouse and keyboard) in Illustrator 5.5 on a PC. I love guinea pigs and I don't see enough articles about them on Slashdot but I hope there will be one, and a future full of guinea pigs here on this site."
21eldavojohn used GIMP 2.8 and about a half hour of his time on dirty dirty Windows 7 x64 to bring you this tessellation. This is a friendly reminder not to drink while reading "Godel, Escher, Bach" nor should you secure your tinfoil hat too tightly to your gulliver -- either may cause delusions of grandeur as exhibited in his posts.
22Penurious Penguin presents "another animated gif which spells slashdot in Morse Code in a font named 'Radios in Motion Hard.' ...Then 'SLASHDOT' appears, followed by the number '15' in my own Morse Code overhead. The 'SLASHDOT' is my own makeshift font as well."
23Already 11 years? Only 11 years? Does it inspire nostalgia, fear, hate, lust, resentment, or indifference in your soul? Christopher Petroff contributes today's logo, "styled after Apple's iPod advertisements--for the 11th anniversary of the iPod's initial announcement."
24Philip Ronan's logo for today is very topical; it mourns the end -- today! -- of Ceefax (see, the world's first teletext information service, which has been around longer probably than have most Slashdot readers.
25Nathan Bebb, of Illyriad Games Limited, writes "I wanted something to depict both space and the space program for this particular date. On the 25th of October of this year Saturn is in conjunction with the Sun (i.e. this is the date that — when viewed from earth — Saturn is exactly on the opposite side of the Sun from us): (See It also happens to be the celebrated anniversary of the 1671 discovery of Saturn's moon Iapetus, by the astronomer Cassini (see So I used both a variation of the NASA font and Saturn in the logo. Also, what is Saturn but a slash and a dot?" Made with Photoshop vectors.
26Artist Barbara Selber digs into the electronic nostalgia history vaults with today's logo, with this nod to Pac-Man, which is right now (barely) twice as old as the site you're reading now. Made with Photoshop and Image Ready.
27In the grand tradition of circuit board art, Ricardo Falletti has neatly hidden the Slashdot logo in plain sight, and efficiently soldered in the name.
28Artist Stavros Vagionitis explains today's logo: "Oct. 28 is a national holiday in Greece. It is celebrated in Greece, Cyprus and the other Greek communities around the world to commemorate the rejection by Greek people to Mussolini's request to allow Italian troops to come into Greece at the beginning of WW II. The result of this stern message was powerful, and in the end, helped to maintain Greece's course of neutrality for generations to come. It is known as Ochi Day or Ohi Day, which Ochi (Οχι in Greek) means N." He used GIMP and the PhattPhreddy font.
29Artist Ignacio "Nacho" Marquez writes from Argentina: "As with many of us that grew up in the '80s my first encounter with a computer was with an IBM XT, and the memory test was always a teaser. I used DOSBOX in Hercules mode to get the font, and the animation was made in GIMP.
30Menno Hellinga turned 'Slashdot' into a barcode. Writes Menno: "I made a postscript file containing the barcode with GNU Barcode and then copied the barcode into the GIMP for some final editing, all on my Archlinux laptop."
31Sean Murphy fades us back with this zippy animation to the Slashdot logo we're used to. Many thanks to Sean and all the readers who've contributed logos for this month -- impressive.
We were gratified and overwhelmed by the excellent ideas that readers had for ways to make the Slashdot logo look a little different each day of this month -- it was great fun to view them, and frustrating to turn many of them down. All of the artists whose work we selected will be getting an 15th anniversary T-shirt, and one of them will get a Nexus 7 tablet as well. We want to show off a few more of our favorites, though; below you see some more of the clever takes that readers had on the old white-on-green flag.
