What type of paper should I do on Leonardo da Vinci?

I'm doing my history day project (a 1500 word paper) on da Vinci. The theme is "the individual in history." I'm considering doing a creative piece, but nevertheless, da Vinci had so many accomplishments that I'd like to zoom in on one aspect, but I'd like to do something a little different as well. Any ideas as to how I should go about this?
