Game two from a seven-part series developed in my final year at UCLA. Based entirely on the number 7, each game was built off an arbitrary (and honestly convoluted) chart that featured interwoven sets of the number seven throughout the world. The original installation featured a wiimote controller and was connected to an interactive piece about synesthesia (that was then used to generate seven unique levels). I've managed to get a few working in the browser if you're interested in trying it out (though I will say these games were more "fun" to make than they are to play. They are VERY challenging).
This game is about creating the perfect union of sperm and egg; however unlike your competitors, you are going to do it without eating your way through. To obtain entry to each concentric level of the egg you must "sing" to the central egg queen. If you sing to her enough she will dispense a token that allows you to gain entry to one more level. "Taunt" the other sperm in order to distract them from your mission and buy yourself more time. Remember that you also can use the mouse to slide the egg around to either make singing easier or reduce the other sperm's ability to eat away at the egg.
Also, if you're interested at all in the theory behind these overly crazy games here's a video from a presentation I gave at the first UCLA Game Carnival event:
