Solution to Classic Concentration

This is a game of Memory, similar to the old TV game "Classic Concentration": Find a pair of matching icons to remove those tiles from the board. There are three levels to the game; once all (or most) of the tiles are removed, you can clearly see the underlying image of a person. Searching for this image quickly yields his identity: BOLTZMANN.

The shortcut for this puzzle is to view the source! In the html source for the puzzle page, you can see a link to the underlying image, bypassing the entire game.
