couple of updates to add ... http://members.evolt.org/mccreath/evolt/cubes/ Dex has provided a PSD file, and I created versions of the gifs with a gray background and a white background. I think the transparent one looks the best and is also the most intuitive. As for the scale, I like Dan's point that getting some kind of recognition early is important. Dan, are you planning on including the power cubes on the user's page? David
