Attached is another rotation themed cube button, simpler in design than my
Rubik's cube button. This cube consists of 8 smaller cubes, with each face dividing into 4 squares, evoking the Windows 8 logo. Hovering over the button will cause the 8 smaller cubes to float apart slightly, and the entire assembly to rotate backwards by 90 degrees, whilst initiating a colour tranisition from light blue to hot pink. Pressing the button will then change the cube to orange. The image contains 11 frames, 9 of which constitute the hover-state animation, the first and last frame being designated as the default and pressed-state frame respectively.
I personally recommend setting the button size in Classic Shell to about 40. If anyone would like a modified colour palette or the animation speed increased/decreased, feel free to drop me a line.
