Help fund a native Linux port of the Torque3D engine and editor.
The makers of the recently MIT licensed Torque3D engine are currently raising money on IndieGogo to do a complete Linux port of the game engine and associated tools (including the editor). This would be a tremendous boon for the Linux gaming community (particularly game developers), so I'd strongly encourage everyone to head over there and donate a few currency units to help them reach their funding goal. :)
Note: IndieGogo has several different types of project funding. In this case, their project won't receive any money unless it's fully funded, so you don't have to worry that your money will fall into a black hole if the funding goal isn't met.
