osu! (clicky) is a PC remake of Elite Beat Agents/Ouendan for the DS, and it's really polished and has a lot more features than the originals. There is already a port for the iPhone (though lacking in features), but the Pandora seems like it would be the perfect platform for osu! - unlike the iPhone it has a stylus, and the screen size and resolution are perfect for the game.
Any fan of rhythm games would like osu!, it's completely touch screen controlled so it would be perfect for any device with a touchscreen (and a stylus), even though most people play the PC version with a mouse, the originals were played using the DS touch screen.
UPDATE
He won't release the source code but he did provide the documentation for the beatmap file format here. I might attempt a remake myself, but if anyone is interested we could form a team, the end result would probably be better that way.
