Create own mouse pointers, fonts, window design etc.

Hi everyone,

I just came to know about windowing system, where we can draw our own mouse pointers, our own logos etc.

By using Desktop Environment, we can design, our own folders, icons, windows, wallpapers etc.

People who are interested in designing new OS can make use of this. May be after some time I will also try. Just go through this wiki link and if you are interested its really good.

Please let me know if someone is starting new Operation System. I will also contribute.
