Out of sheer boredom, I began rolling a smooth marble around the screen of my Pocket PC (which, I might add, has a screen protector) while in the “Notes” program – and I came up with some cool designs.

If you too suffer from boredom, try out the above, and let us know how it goes. And if you’re truly daring, post a screen shot of what you (and your marble) came up with.
