Kickstarter. There has also been several threads about crowdsourcing novels on the Kindle Boards lately.
Today, an indie author I admire, Lindsay Buroker, wrote a blog post about the whole crowdsourcing thing. She explains a little about what crowdsourcing actually is and how you can use it to fund your own novel as well as how she plans to use it to fund her podiobooks. (Podiobooks are audiobooks delivered as free podcasts.)
A very good read, especially if you're an aspiring author wanting to self-publish and wondering where you could get some money to fund it.
I would like to add a caveat for those thinking to use Kickstarter to fund their projects. If you're outside the US, you won't be able to use it. (People outside the US can give money towards projects, but can't create projects themselves.) Instead, consider Indiegogo.com, which does allows people outside the US to use their site for funding projects.
