I recently stumbled across the site Kickstarter. It’s an interesting way to raise money for a creative endeavour you want to do, for instance, make a film. You set a time limit and a goal, and encourage people to donate to the cause. If you reach your goal, excellent, you can go on and make your film. If you don’t reach the target, though, no one pays anything, all donations are cancelled, and you’ll have to go back to the drawing board.
