A teaser shot 100% on GoPro HD cameras, showing what can kind of 'bullet-time' effect can be accomplished with the worlds first GoPro HD Video array. Firing off dozens of networked still cameras in a single frame is a technical hurdle for most, so a more popular idea is to extract a single video frame from each video clip. This is a time consuming post process, which looks like how this project was pulled off. I can't be sure, but a similar project was done using DSLRs not too long ago. [Thanks Jason]
