There is the excellent code by the great @Informatix :

Just for "fun". If you rotate the disk image you posted, which has an illumination effect, the end result would not be perfect; who knows if it would be possible to illuminate the disk at runtime (very very hard!).

this works fine to rotate, but i really dont know add FORCE/ACELERATION on the touch, for example: if the user rotate fast with the DISC with finger it need give rotate 5x or 6x times or more.
if user rotate slow the DISC with the finger it need rotate only 1 or 2x

thats i dont know how to make, you know? can post a example if yes?

I should read the @Informatix's code. Take a look at it to know if that is possible.
