Ds Vj

Hello Everyone. I ran into this _nasty_ video:
http://www.youtube.com/watch?v=As-jKn1Mm0w&eurl=

My question is: which app could the DS guy be using to control the visuals? is there something like an Arkaos or Resolume (vj apps) clone homebrews for the DS?
I'm really interested in this stuff as I'm a VJ, and I own a DS, and.. well, that is way too cool.

I know this may be a fake, but please if anyone of you knows anything about this please let me know.

PS: thinking of it, even if there is an homebrew app for mixing video loops, the things that amazes me is how they routed the DS video output to the projector...
