Apparently "GoPro" camera's have made it possible to shoot your own 3D film's, on their website in states:
"The 3D HERO System allows you to combine two 1080p HD HERO cameras into a single housing to record 3D video and photos while simultaneously recording in 2D. A synchronization cable plugs into the rear HERO Port on both cameras to join them together, enabling both cameras to record video and photos in perfect synchronization." So 2 of their 1080p HD camera's would run you around $270 each, plus the 3D HERO System that is actually quite simple and only costs $100 plus whatever mount's you may want. GoPro also just acquired "CineForm", which will allow you to edit the footage for free.
