Video Projection Tools (VPT) is a projection mapping software for mac and windows. This video goes through most parts of the interface of VPT 8 and compliments the online manual. Although it is not very inspiring to watch a video showing the VPT interface for an hour for a software which is all about projection in three dimensional spaces you will find it useful.
