I don't think anyone won the last challenge, which was for making a mechanical camera, because they kept extending the deadline. The requirements for the camera they wanted were pretty stringent. If they were willing to accept different resolutions image shapes then a hacked antique IR camera would win. Old IR cameras mechanically raster scanned a single detector over a scene fast enough for 15 fps video.
