A brief history of pretty much everything is a 2100 pages flipbook made by 17 year old animator Jamie Bell. Here are a few words from Jamie Bell page on Youtube:
This is the final piece for my AS art course, a flipbook made entirely out of biro pens. It’s something like 2100 pages long, and about 50 jotter books. I’d say I worked on and off it for roughly 3 weeks.
Song is French Cancan by Jaques Offenbach.
Additional sounds credited to Valve, specifically from their game Team Fortress 2.
Other stuff is from the 300 trailer and O Little Town of Bethlehem.
