Mine is a spoof design I created many years ago based on the old soviet hammer-and-sickle seal. Not because of any philosophical or political beliefs, but simply because I like the aesthetic. It’s a bit small on this site, so if anyone can’t make it out, it’s a can of spraypaint and a paint roller in place of the hammer and sickle, surrounded by the wreath of wheat, banner and red star.
You can see the original drawing I did for it in the right column in this picture: http://img.photobucket.com/albums/v64/Joey-Poey/Art/gripartretrospec.jpg
