OtaClock DS is pants-wettingly great

Let the kids with their $600 consoles have Metal Gear Solid 4. We've got the best part of the game -- Otacon's desktop clock application, the OtaClock. And it's totally free! In case you're worried about spoilers or something, don't be: the OtaClock was revealed in the TGS trailer in 2005, and released as a PC/Mac desktop application soon after.

Homebrewer madcat1990 has adapted the app into an alarm clock for the DS, which deviously requires you to solve a math problem before the alarm will shut up. It's an appropriate tribute to the pseudo-Oedipal, incontinent otaku Otacon, one of the most complicated characters in Metal Gear's extraordinarily complicated cast.
