Have you ever thought about what it would be like to be a goldfish?  Boring, right? Confined to the same space, swimming in circles all day, never a change of scenery.  Thats no way to live.  Maybe it's time to get your pet fish some wheels!

Check out what these folks did for their fish.  The fish is now mobile and can control which direction it goes using computer software.  Pretty sweet, huh?  Clearly there are some issues that need to be worked out, such as some sort of lid for the fish bowl/tank.  Also, you'll have to pay more attention to where you are walking, but your fish will be forever grateful for improving its quality of life!
