Prince of Persia and the birth of motion capture...
Jordan Mechner, the creator of the original 1989 state-of-the-art animation
game Prince of Persia, has recently released the videos he took of his brother that he used for the animations in the game. When this game was released, it really took animations on the PC to a new level. For those that remember playing the game, I'm sure you'll recognize the moves performed in the video—especially his brother "struggling" to get up the wall.
It's pretty impressive to see the original footage that lead to the ground breaking animation. It's basically the birth of motion capture in video games.

Gary Gygax, co-creator of Dungeons & Dragons and one of the fathers of tabletop role-playing games, died on Tuesday at the age of 69. He had suffered from heart problems.
