since body painting is pretty popular thing on the playa - what about posting out there on the burning man tribe to see exactly how much paint is needed - also figure out exactly what you are going to do

- airbrushing? really groovy - works awesome with stencils - see if someone has an airbrush they can donate for the use and talk to people on tribe that have done this and see how much paint you will need

- latex? whole other ball of wax (ha) that has a massive clean up issue - and where does all that go when it comes off, plus its really pricey - and do you want to educate as well as paint? it might be more a hassle than its worth

- crayons - cool, but limited...but combined with paint might be neat

- regular paint - talk to people on the burning man tribe that have done this before, let their experience guide you instead of poking blind in the night on what you might or might not need

also - a fun thing to do if you really are jonesing for the body decor without the big mess - non-toxic highlighters on skin glow under the blacklight and disappear in the daytime - a great way to decorate without over committing

- just some thoughts, instead of guessing around!
