I already had most of the components laying around, but I did buy power supplies for the Pi's. I also have one in the attic running dump1090 and the upload client for flightradar24 - it has no case either, and I'm using a <$15 RTL tuner from nooelec.com.

Flash Card: $6
Case: None - taped naked to the back of the TV
Power: About $7
HDMI Cable: $3
Ethernet cable: already had tons laying around, or could make one for $1

Grand total: $17

Well, here's the tl;dr of TFA: Social media is the starting point. Hence the Arab Spring—you use Facebook or Twitter or whatever to spread your message and/or propaganda, and then accrue those with personal willingness to march and coordinate action through the net. Five dictators have been overthrown in the Middle East since December 2010 (as well as uprisings and protests in more than a dozen other countries) following social media germination, so clearly it's viable for that. Unfortunately this means it's also a single point of failure, as shown in Egypt when they depeered from the rest of the network in early 2011, easy to infiltrate and possible to manipulate.

3D Display Uses Misted Water 65

An anonymous reader points out work at the University of Bristol into interactive, 3-D displays created by projecting light on misted water. "These personal screens are both see-through and reach-through. The see-through feature provides direct line of sight of the personal screen and the elements behind it on the tabletop. The reach-through feature allows the user to switch from interacting with the personal screen to reaching through it to interact with the tabletop or the space above it. The personal screen allows a range of customisations and novel interactions such as presenting 2D personal content on the screen, 3D content above the tabletop or supplementing and renewing actual objects differently for each user."

Behind every great computer sits a skinny little geek.
