[A camera that shoots 300 frames per second](http://gizmodo.com/gadgets/super-slo_mo/casios-exilim-cam-lets-you-shoot-300-frames-per-second-mythbusters+style-295491.php)
Unfortunately it only does it in pretty low resolution, but it could be quite fun. But my real question is how long it can take pictures for – 300fps is no good if you can only get 10 frames!
