awesome, simple and fun project to expand photographic horizons. A great project for an advanced photography class at the library, or for the photo buff who wants to expand his/her horizons.

just cut a piece of black cardboard/posterboard(to block the light) to the exact size of the inside of your DSLR/SLR lens and cut a shape in the paper- e.g. a star, squiggle, or letter to blur the image in that way.
