It's an implementation of some standard GL demos for testing puropses but if you didn't know that, you wont want it. Does exactly what it says.
"opengl demos from RedBook Samples", "for developers". Gives what it said. Why do you guys expect more??
What's with the ads?
What is it jus picsz?.???.?
Dissapointment. OpenGL Demos much, much better.
All demos force close on motorola droid. Not very useful. Next time check what extensions are available on your hardware...
