There is more art at Burning Man than you can even see. Thats because a huge majority of the people that come to BM are artists. So everyone is creating art be that their clothing, bikes, cars art installations or camps them selfs. Basically everything is artistic at BM.
This is a huge wall consisting of hundreds of panels all hand painted by BM artists and yes of course some of them paint naked.
Its great to have walls when they are hand painted inspired art!
Life is a creation∞
