The interesting detail I read somewhere else that is not mentioned in the article is the source of the cool idea at the core of this. If you watched the Planet Earth series (or saw any of the promos that were run 24x7 on the various Discovery channels) there were some very, very cool shots of sharks jumping out of the water while catching seals. To make these shots the filmmakers had to invent a new camera technique because it was too difficult to try to time the shot to get what they wanted. The digital cameras were attached to what was essentially a big ring buffer and were constantly running. When a shark breached the guy on the camera would press a button and the buffer (which had the previous X seconds in it already) would dump and new data would start going to disk to complete the shot.
