My Common App essay was basically about how I grew up with English and Spanish, one eventually taking the place of another, and blahblah. It was kind of like a little soap opera. XD So that one was unconventional. I basically talked about having an affair with one of the languages, too.
My other, college-specific essay was kinda odd too. It was set like a story; I found out I was invisible and then went on to describe what I did during the day (showing my character, hobbies, desires, likes, etc). It dealt with my cultural identity, heritage, and all sorts of good stuff.
My UMich conflict essay was about how little kids are turning into little prostitots. I talked about Barbies, Bratz, the media, family values, and such, in a sarcastic, tongue-in-cheek kind of way.
With those, I got in at every place I applied. Brown, UChicago, Cornell, Swarthmore, UMich, and BostonU.
