Get an 8"x10" photo print of your favorite picture (don't use an inkjet or the colors will die). Modge podge it onto an 8"x10" peice of wood. I used the thinnest I could find. Cut a border off the outside, and glue the border onto another 8"x10" peice of wood. Then cut the rest into peices.
I haven't tried this, but I suppose you could make puzzles by using this method to get the picture on the wood. It looks really cool.
