Here's an interesting 'website browser' built in Javascript which fakes a 3D browser environment. It displays screen shots of sites in a floating cube which you can navigate in 3D through. You can click on a site to full screen it and make it interactive. I think he is just using Javascript to fake the 3D and not SVG.
Here's a video of a guy playing air hockey with a robot he built. The robot tracks the puck with a camera and then uses it's harm to hit the puck away. It seems to be pretty good if a little slow. For example, it seems to have trouble recognizing when the puck is still on it's own side of the line after hitting it.
Guy launchs a remote control aircraft from the back of his car, controls the RC plane with some VR glasses and remote, takes some aerial photos from the RC plane, and imports them into Google Earth for a good time in this video. Everything he's using seems like just off the shelf hardware that he's put togather himself.
Here's a video of an remote control B-29 model carrying a remoted control X-1 rocket plane model. The B-29 takes off and drops the rocket plane. The rocket plane ignites and shoots upwards before coming back and landing. The B-29 model does a few fly bys of the camera including one where it flies by upside down and does a backwards loop. Both planes land safely verses other videos where they fly a big model and then crash it by mistake.
Here's a video of a guerilla 'marketin'g tactic from Holland where they drive around with a projector in their vehicle projecting a skateboarder riding around on the top eve of buildings. It's a cool effect but didn't seem like it would be very effective. How long until we see Sonic running around NYC on buildings?
Here's a jetski like watercraft which is complete covered and shaped like a dolphin. It can only submerge up to two feet but it can do rolls and dives within that two feet. Additionally they claim it can jump up to 10 feet out of the water and is powered by a car size 300 hp engine. The cockpit glass of the watercraft is from an F-18 and is about half an inch think which lets it withstand it hitting the water. In the photo on the main site for the watercraft it looks to have two seats in it but in the video it seems like it only has one seat.
Here's a video of a Christmas light setup syncronized to music. Apparently the score is Trans-Siberian Orchestra's Christmas Eve Sarajevo and the lights do a pretty good job of accenting the music. Not all of the lights are set to the music as some of the front white lights on the left and right side of the setup are not syncronized. The real question is does this guy have that thing going on the entire time or he only setup the syncronization to record it. It probably drives the neighbors nuts if it repeats over and over like that the whole time for a month.
Here's a demonstration video of what can happen when a lithium ion battery explodes in a laptop. The video is a little slow so you'll probably want to click forward past some of it. In any event the first 'cell' in the battery explodes releasing some smoke and damaging the casing. The next cell explodes because of the heat from the first cell and blows a hole in the top of the cashing. Each cell explosion is progressively worse than the last one with the fifth or sixth cell explosion throwing out a pretty good size jet of flame.
