People w ill not condemn you as a freak for wearing nothing but body paint. This is not a performance. One does not go to Burning Man to watch and be entertained. One goes to participate and be a part of the spectacle. You must immerse yourself in the experience by being a part of it, not just by observing it.
Some people build elaborate artworks.
Some come in elaborate art vehicles. But sitting there and being just a spectator is taking without giving. I'm not creative. It takes so very little to contribute. You don't have to create an 11 foot diameter sphere of ice that spouts flames from the top and doubles as a sundial during the day.
