| When has the difficulty of a task ever dissuaded UCB grad students? (Ok, actually a lot. But ignore that for now.) Let's watch a goddamn DVD on that 9-panel display! | **CAUTION:** the movie-streaming system described below is fragile, at best. \\ |
| |
| **Outline:** we will use a desktop computer to play the DVD and stream it over the network to the Mac 9-panel computer. | |
