Here's a crazy video of a two legged robot that balances and walks upright on it's own. The information with the video also says the robot learns the more it balances. They also show a second robot trying to push it over and it corrects it's balance.
In this interesting video they demonstrate a working orithopter model which flies around a school gym. A orithopter is an airplane that flats it's wings like a bird. It's hard to tell what is powering the flapping wings in this video. It could be a rubberband or a really small battery motor.
This video is from an auto show in the UK where they had all the pieces of a F1 car split out and wired into midair like a 3D cutaway. The person recording the video walks completely around the suspended car. I assume the wire goes from ceiling to floor so that the pieces don't swing.
In this video a couple people fill up a fish tank with some heavier than air gas called hexafluorid. Next up they float a tinfoil boat on top of the gas and finally sink the boat into the gas by filling it with the gas.
Apparently it went up to about 295 feet and then they brought it back down. They have high resolution photos over on their website plus additional videos.
Here's a video of a prototype computer input output device which is designed like a paint brush. It has a built in video camera into the head of the brush which allows it to pick up "video textures" or still colors and textures. For example, they show the paint brush recording someone blinking their eye and then painting the eye blink texture on a computer screen canvas. It's hard to tell if the screen canvas is touch sensitive or not (I think it is) as it shows someone smudging one of the images with their finger. However, it's possible that the paint brush device just records itself drawing. It picks up all kinds of textures like this fur print off this hand bag and works exactly like a paint brush after that. Watch the video for a better visual explanation.
Here is a pretty cool do it yourself project that turns an optical mouse into kind of a reverse trackball. Basically it is an optical mouse shaped like a piece of soap that is in an elastic/silk/polyester bag. You can rotate the mouse inside the bag like it was a wet bar of soap. You can also move the fabric of the bag with your thumb over the optical sensor causing the mouse cursor to move around. The video itself explains it much better including how make one for yourself. It seems like it works pretty well from watching the people in the video play games and navigate windows with it.
Here's a prototype screen interface from Microsoft which was demoed at the CEBIT 2006 conference. It's very similar to the interface from the movie Minority Report. I believe they are using a rear projector (though it's possible they are using an LCD). Basically there is a piece of glass with the display on it and then behind the glass is a motion sensor which tracks the user movements (I believe). There is either an LCD sandwiched in between two pieces of glass or a rear projector. I also think this is the interface that Robert Scoble talks about in this interview.
