I was actually a bit dissapointed there was grey-scale at all. Just using different chars for that (".+*" for light through dark grey, "|-\/" for edge features, f.ex) would have been cooler, IMANHO.

\begin{aside}
Back in my grad school days I was doing programming involving image compression techniques (Hadamard, Haar, DCT, etc.), Viterbi encoding, etc. for use over noisy channels and the only output device I had easy access to that could produce a viewable image was the monster IBM band printer. We had some programs to produce output like the hasciicam only it used overstrikes to create much of the gray scale levels. (Other folks eventually got used to seeing before-and-after images hanging from the walls like wallpaper.) We eventually got (for another study) a thermal printer but was a pain to use (serial input from the mainframe, required expensive paper that turned yellow green after a while, etc.) This brings back some memories.

Being one of the Inventors of this (Beer Inspired) technique I have have a a lot of intrest in it.
Also, There will be a new website comming up in the near future http://www.lavarand.org (no link since it is not on the air yet) with new an improved access to a lavarand system.
Note the the intrested, the patent only covers using the data to seed a pseudo-random number generator ...
Cool, but not really ASCII (Score:2)

The ascii cam is cool, but it doesn't really use ascii because if converts the ascii to png. Because of that it doesn't really help to limit bandwidth, a real ascii stream could give a streaming fluent image even to modem users, that is completly imposible with this png streaming, you couldn't watch the stream with lynx,too.
I think they should have used telnet for this stream.

Why on EARTH is the screenshot encoded to a PNG file? Seems like the most bandwidth-efficient way would be to just send the ASCII!
Oh, wait... I don't have ANSI terminal emulation enabled in Netscape... nevermind :)
Ahh, the good old BBS days. It's great that they now have "live webcam" functionality for systems like that, 10 years after they're useful :)

Y'know, this kinda ascii could be good random noise input for a cipher."

Yeah, there's really nothing better for cryptography than a repeating stream!

Linux is only 5 years behind... I used something when I worked at SGI with my Indycam to display the output of the camera in an xterm in ASCII.

I found this webpage (circa 1995) detailing the software. Congrats Linux you've revolutionalized the computer industry again. I hope you at least stole *some* of the code before creating this new and wonderful tool...
