Two games recently started "Kickstarter"-style campaigns on IndieGoGo with part of the offer being "becoming open source":
There are few alternatives of making money with open source game development that comes to mind:
Oh, and Bitcoin! We need more Bitcoin action! FOSS game developers! Open up a wallet on for example blockchain.info and share your wallet address! As for Flattr... I don't know any more...

- Monster 2, a JRPG which has been open source for a while but then was closed during a upgrade of game data/content, will be released under the Give it Your Own License, License if it reaches its goal of USD 1500,-.
- Tumblegonk, a yet unreleased simple puzzle game, will be released under GPL if it reaches its goal of USD 850,-.
There are few alternatives of making money with open source game development that comes to mind:
- Make the engine open source and the game data freeware but sell it on closed platforms, like Frogatto (iOS version is for-pay).
- Port existing open source games to closed platforms like in the case of Word War Vi (iOS version is for-pay - read the original developers' thoughts on this in this forum post).
- [Warning: self-promotion] Sell additional, proprietary game data extra, while having the engine and base assets available under free licenses, like Nikki and the Robots (Story Episodes are proprietary and for-pay).
- Donations. Some open source games accept them. The only game with compelling data on this is FLARE. I don't know of any open source games that fund full-time development through donations.
