A semi-tradition amongst myself and some of my geek brethren. When there's a break that we're not going home for, we usually take a weekend to do nothing but watch weird anime continuously with no sleep for forty-eight hours or so.

For the upcoming Easter Break, we'll be watching, in their entirety, the following series:
Neon Genesis Evangelion
Serial Experiments: Lain
3X3 Eyes
Key The Metal Idol

This break will also mark our first try at making Magic Coffee.
Update: The Great Anime Mind-Fuck Weekend has become an official event of the Marist College Anime Society. We lock ourselves in a theater with a video projector for 52 straight hours, watching nothing but the finest anime available, with the occasional break for sushi.
