Odd Ball Exercise Ball
Sadly, the space ball computer game Collabowobble isn't available yet, but you can still get an Odd Ball and bounce around. I had one when I was little and it was called a Hoppity Hop. I'm sure I didn't think of it as exercise back then, but it's probably a good workout for the legs and glutes.
Available in orange or blue for $26 at artecnicainc.
