A long long time ago in a galaxy far far away I made a vector of BZP's Tohu logo. (Some of you may or may not recognize it as the Steam group's picture.) I never got around to perfecting it (proportions are off and coloration is downright bad) and probably never will (I was originally planning to release it in GD with much fanfare), but if any of you want to use it, go right ahead.

The image was created in Adobe Fireworks, if you open it in Fireworks, the actual vectors should work. It did for me, but I don't have it installed now to test it out.
(I used a lot of parentheses)
