Looking for some choice Live Rock pieces

[ScubaSteve]

I acquired an old biocube from a friend that I'm going to set up at work. I've decided to experiment a bit with the aquascaping and want to try a bonsai-style reef. I'm on the hunt for some nice shaped, flat or pillar-like established life rock (sans aptasia!) to assemble a structure. Haven't had much luck at the stores looking for the pieces I need so I thought I'd throw it out there to see if anyone had some pieces in their sumps, etc that might fit the bill.

Basically, I want to make a miniature version of this guy...
