I'm contracting with a guy I found on instructables to make me lots of those acrylic hats. Like the little record player one that the girl with the hoverboard had. Those cost a few pennies though, so I'll need your help for financing.

http://www.mirajcaps.com/ Used to sell lenticular BTTF hat replicas but, the manufacturing was too expensive to justify further production. Their site hasn't been updated in years.

They have those hats at the local comic store. Also on amazon. It's pretty cool to read the reviews- people say they get a lot of recognition when they wear them.
