Here's mine. You ever play Erotic Photo Hunt? It's a game on those touchscreen video kiosks in bars. Each round, you're shown two almost-identical pictures of a scantily-clad girl. You've got a minute to find the 5 subtle differences in the two photos. (It's embarrassingly addictive -- for both men and women alike.)
Build a web-based version of that. After every round, the player is given two options... "play the next round" or "see more pictures of this girl." The latter is a paid link. Weekend hack => goldmine.
Hey, thanks! Why am I not doing it? Um, all I can come up with is, "I'm working on other projects... that are more complex... and less of a sure thing." =P
Anyways, if you're inspired, go nuts. Lemme know if you want any help building it. Also lemme know if you want to hear the rest of the idea. (I think Phase 2 could get you one or two patents, and Phase 3 could disintermediate some dirty old men.)
Uh, is it weird that I've put so much thought into this?
