As part of Ground Tournament 4, we and the other teams gave presentations about our projects. Although the presentations were recorded, we were not notified of where (or even that) they had been posted. However, we recently came across the presentations video when looking up CubeQuest information.
The video includes our GT4 presentation, as well as the presentations of the other GT-4 competitors, along with remarks by CubeQuest Challenge Administrator Jim Cockrell.
Note that the screen capture recording of the slides seems to be slightly out of sync with the video recording of the speakers.
