I collect Disney pins as well. A friend gave me the idea of displaying them all on a cork board, and taking a picture of the board before I go to the parks so I know what I have. I love the ride and park pins, and I usually get a pin with the year on it. Sometimes I grab the character ones, but I've gotten less of those lately.
I have a small collection of TRON stuff, too! Two action figures and my light cycyle flash drive. I add stuff slowly to that collection, but I love it!
And my Monster Highs, too. Can't forget about them!
