Tumi's 3D Gravity - Version 1.0 This sweet animated cursor set created by Tumi, an author for Pankaj Arora Software is beyond amazing. It defies the laws of gravity. Notice how some of the cursors have animated structures that move in defined orbits by some mysterious force of nature. Okay, so they are just cursors but they help build a stunning atmosphere in Windows and boggle the mind a little.
