My friend David Steinlicht recently posted a time-lapse movie showing the day-to-day progress of his award-winning entry to the seed art competition at the 2008 Minnesota State Fair. It depicts a scene from the video game Grand Theft Auto (of which he is an avid player) with a can of Festal sweet corn. In seeds. Not your typical seed art subject, but David is not your typical seed artist.
The speed at which the work progresses is highly misleading. To put things into perspective, David includes video of the process in real time after the time-lapse part.
