Ever since I got back into town and saw RLG1034's posting "aaargh," I've been thinking about pyramids. Teri's formula approach got me very confused, so I built my shader out of Eric Winemiller's bricks shader element. I had to build the pyramid in four sides, though, using cube face mapping to get the bricks to line up properly. Once I did that, I just had to make a pic. Anybody else driven to Egyptian things? (Or Alan Parsons Project songs -- if anybody gets the reference....)
