Through the Independent Gaming Source I found out about A Tribute to the Rolling Boulder, an indie game by Petri Purho.

In it, you play the boulder from the first Indiana Jones movie, and you need to defend the honor of two fertility statues from the lecherous advances of brown-hatted archaeologists. I presume it's a PC game, so I haven't played it myself, but the concept is hilarious. Be sure to check out the video (skip to the end if you're getting bored, it rocks).
