I've been exploring Kickstarter recently and it's interesting. Kickstarter is a website that was established in 2009 that is used to help creative projects get off the ground. Users submit their ideas and they are accepted or rejected. Once accepted, you set up a goal of how much your project needs, set up incentives, and start getting your project out there. Other users then can donate to your cause and help you meet your goal. Money only exchanges hands if the project is successful.
They have a good number of categories including gaming, technology, books, film, and others. I just came across this site and a few of my Twitter friends have used this with their games and other projects. I recommend checking this out whether you have a great idea and need funding or just want to check out and back some great projects.
