So there is this guy that does awesome art and his name is Phil Hansen. He uses random things like matches, candles, leaves, starbucks food to make masterpieces. He has a website : http://philinthecircle.com/ and you should just take a look at the awesome things he has made.
He did a portrait of bruce lee that i thought was fun but he only did it by karate chopping the canvas. http://www.youtube.com/watch?v=CbvSms-1yj4&feature=related
Take a look. He has plenty of other videos as well, like using wine to create a piece of art of amy winehouse. He's super creative and fun to watch.
