Jet3d Game Engine

From what I gathered from the license it is available freely, source included, to anyone that wants it on the condition that you must release any source code changes you make along with any product you produce with it. You can also release a product with unmodified binaries they provide, or you can pay to license the engine and you get to keep your modified source to yourself." Wow! This looks sweet!
