ProteinDS app enables DJ-style scratching on Nintendo's DS

Not like we haven't seen Nintendo's DS used as a music maker before, but this variant may be the most amazing to date. yarglaaaafr's ProteinDS application is currently in demo mode, but judging by the demonstrative video waiting after the break, it's remarkably solid as-is. C'mon, it's a tool that enables users to scratch up tunes via the handheld's built-in touchscreen -- how could Mario not approve?
