Experimental support for 10.7. Warning: Not all computers running Mac OS X 10.7 can run this app. Only those that support OpenGL 3.2 or higher (that's the same ones that can be upgraded to 10.8 ) qualify.
I downloaded all of the files, but I'm unsure how to get it to work (like what files I need to open in order to get it to run.) Sorry if I'm being a pain in the ass, but I've never used a program like this.
