The wonderful Japanese photographer Natsumi Hayashi has a great website called http://yowayowacamera.com/ in which she documents herself levitating in different environments. Although easy to do, I think these are really fantastic! Here are some examples I really like, but there are really a ton to choose from and you should visit her site:
On her about page, she describes the equipment she uses so be sure to check that out if you want to try your hand at doing it. Here is another admirer of Natsumi, Kai from Digital Rev, who made a video on how this is done. It is very funny and entertaining as well. Remember, keep photography fun!
