The epic, 3,099-panel XKCD comic entitled "Time" has finally run its course. Back in March, BoingBoing reported that Randall Munroe’s strip — a favorite of Verge staffers and Richard Dawkins — would be unveiling new frames in the series one at a time, as it told a story of sandcastles, exploration, and a quest to understand the sea. If you’d rather not click through all the panels individually, Geekwagon and Aubron Wood have players that let you absorb the entire opus in just a few minutes. We won’t spoil the ending for you.
