by the way, this is what Metafilter had to say about this:

Ever since someone wrote software to teach geeks to dance, the DDR craze has enjoyed quite a number of spin-offs. Karaoke Revolution got people singing. Donkey Konga is the same thing but for bongo drums. Guitar Hero for the PS2 has gotten rave reviews and while letting you rip some guitar solos. Christian game makers are even cashing in with Dance Praise. But nothing comes close to the coolness of Accordion Hero. Squeeze hard, die young.
