Stamp made very fast in photoshop. I know it's crummy, but I couldnt find any stamps any other places for this so I made my own. IF you wanna use it, please tell me with a little comment here. Also.. if anyone wants to.. I could take it down and improve it some.
EDIT: forgot to make background transparent, making the upper edge disappear.. should be working right now tho.
EDIT 2: OC = Open Canvas
OC is a drawingtool, mostly known around my circles for it's support for network and online cooperation in it's 1.x release. This feature has been discontinued, hence it's one d##ed buggy tool, but we still love it.
EDIT 3: Feel free to use the icon/stamp wherever as long as a link and preferably credit goes back here.
