I think it's a multi coloured splatter pattern over black with a touch of spray detailing. Looks like it could be the second in a series.
imagine a shelf with all Jackson Pollack style paints...whomever got Shikaruna's Grumpy should buy this as well. Lovely version, do want.
Oh whoops... I didn't know that was considered derogatory (just looked it up). Seriously. I apologize for the joke. I blame it on watching too much Barney Miller as a kid.
Reminds me more of foam carpet padding (the black kind with the multicolored bits) than anything Pollack ever did, but it's great to see a new technique from Mori. Nice to see a new Bat too.
