Barbalee, Undefinable is on my must-have list also. If you like that one, I recommend that you check out Clown Pants (I think it's called Clown Pants, anyway?) and Explosion in the Paint Factory. I think you'll also like Pink Stripe. I'm hoping to get my hands on a TET version of Pink Stripe some day, but I think they're still working with it to stabalize it.
