Man, I don't even notice them anymore. They are the shape I relate to that person. If pt stuck his 'tar on a wall in New York nobody would have a clue what it was, but if I walked past it I'd probably think of pt.
They must be some sort of subconcious testing. Someone probably hacked the forum server and put them up and is now watching us and testing us.
Thing is I can remember what PT's avvy looked like - but Matt's just looks like some blown up sprite from the Manic Miner Era and the top one more like something down the front of my blouse after a tequila session!
