Looking for a project

I'm sure you've seen the photo sets where people take an object like a ball, action figure, or something that take photographs with that in the scene some way. Well, I'm curious to do some of those. I'm interested in some suggestions! Going to San Diego in a couple days for about 9 days, and I think it would be fun to include in some of the tons of pictures I plan to take to also to some item shots. Give me some ideas!
