While everyone was raving about the singing 386DX computer, I though that the Super-I virtual reality goggles Alexei Shulgin had for sale were pretty interesting. For a mere $2499 you get the processing unit and the Future/Retro looking camera/micro display headgear strait out of the Lawnmower Man. It looks like this product took quite a team of people to design, so its DIY factor may be quite advanced. However I imagine that it takes some hardcore embedded CPU DSP makes all this possible.
