When i was in Mexico a few weeks back, there was this one guy down there on the streets that was an excellent artist. He was making really cool pictures with spray paint and then he take pieces of paper and smear and smudge. He was really good. Anyway, we got talking to him, and we were going to get him to paint us a picture of a guy doing a superman in the dunes. He said he's done lots of helmets before too. I think anyone that is good with an airbrush and and is a great artist could do a great job. It may be pricey though i think:think
