I really liked this quick homework assignment for digital graphics this fall. I had a chance to do some really cool photo manipulations. I got a picture of a jar full of water, then did some crazy things to my hair and took some photos of myself as well. Layering different photos and the right editing gives the illusion of my bruised, disembodied head floating within a jar of water, mouth sewn shut.
Unfortunately, because of a computer crash, I lost the psd file. If I can get my old hard drive looked at, I may recover it one day though.
