MeFi has seen a GoPro camera attached to a sword, but after running across a video of one attached to a Hula Hoop (it'll make you dizzy) I decided to look for more and found a trove of sports, most of which are created by GoPro and as such may come across as advertising, but some are independently shot, so put that aside if you can. I'll probably never take up any of these activities, but I get an idea of what they're like via helmet or pole-cam. There's the Base Jump; the GoPro at 80,000 feet (near space); Boogie Boarding Surf; Surfing; Racing up Pike's Peak; Mountain Biking; a Kayak Competition; Kiteboarding; Longboarding; the 2010 Highlight Reel and many more. Damn, now I want one!
Five surveillance cameras capture a tornado hitting Alexander Hardware and Small Engine; tornado was an EF 2 with wind speeds of 120mph.
Reality Touch Theatre at the University of Groningen: "... we turned our existing 3D theatre with a big cylindrical screen into one that can detect 100+ simultaneous touches." [more inside]
The Rolling Shutter Effect: a mobile phone camera is fairly quick, but when the objects you are recording move faster than the scan rate, cool things happen. Mucho previously at MeFi.
