Quick video of me making a Microsoft Vista style logo. I used this for my youtube theme, except the color is different.
*update: for the lines dividing up the square I don't usually use the warp tool, I make a cleaner shape by using the pen tool.
Steps:
1. 3D ball rendering
2. Black square
3. warp square
4. break apart
5. emboss
6. gradient overlay
7. lighting effects on ball + emboss
8.drop shadow. done.
