XCoding..

So I start XCoding. The first impression is that the code editor is fast and very intelligent. If we don't make all the configuration right, it won't even compile. I found color scheme that looks pretty:

I tried to code some GLUT and OpenGL and found out that some functions have been deprecated. But I still can use them anyway, so there's no problem. Here's what I made at the first attempt, still have many things to improve but so far I like it.

I'm still using C++, not the Objective C. Have to squeeze some time learning Objective C and make a better UI.
