One of the best DS games available now has a homebrew Windows counterpart… Meet osu!, the Web 2.0 version of Ouendan / Elite Beat Agents. Here’s a video of osu! in action, featuring the delightful Haruhi song…

With a bit of work, you can create your own levels using your favorite songs and videos. Naturally, you can exchange levels with other osu! players. Browsing the download section, I see user-submitted “beatmaps” for songs from John Mayer, James Taylor, Weird Al Yankovic, They Might Be Giants… even other game series like id@lmaster, Pokemon, Taiko Drum Master and Smash Brawl. So it’s not all j-pop, although the osu! creators clearly seem to favor the Ouendan half of the East/West equation. (Me too!)

Dear Nintendo: approve this project immediately. Make this WiiWare.
