while looking through the august 2007 roblox client, i have found a few things that i couldn't find mentioned on the web elsewhere. I will post most of my findings here. In the textures folder, there is 2 textures, JohnHead and JohnTex. These are the textures for the unused player model. You can find more about them here: RBLX Blog - The Cutting Room Floor. i have also found an unused Torso Mesh that was likely supposed to look like a lego minifigure.
