One of the coolest displays of art that I have seen was henna design - no, really. It was a really cool nature design and was utilized in the form of giving a tattoo. Tattooing is simply using what nature has to offer and using it as a form of expression on the human body. In many cases the natural ingredient is ink. But there is something so quaint and ethereal about henna design that I find it to be simply breathtaking.
