Every pledge gets their name and photo (if they like) in the production credits of the movie. The first 50 to pledge $20 or more will also receive a magical creature T-shirt screen-printed by the prop master of the film.
For $50 bananas you get the Tshirt plus a handmade package - a flash drive (containing the movie) and all sorts of fun, behind the scenes stuff that will come flying out when you open the package. I can do a VHS tape also, if you're into that sort of thing.
For $200 smackaroos, you get the Tshirt, movie pacakage, a print of the official movie poster, and you'll be eternalized in the movie universe because your picture will show up on a wall in one of the scenes in The Aquarium.
