Some robotic...VR...etc links...

So one ongoing project is the ROVIO...well some third party applications have been written for it (as well as an iPhone app). Here are a couple that I haven't tried yet, but look interesting...

Now back when I was a kid...I wanted one of these...Big Trak...you can get them n0w on ebay for not much money...and of course some folks are hacking on them...
