What is the name of this self powered swivel scooter?

Question

Ok so when I was in elementary school, [I am 29 btw] we used to ride these little blue swivel scoot things. If I can remember right it looks kinda like a diamond and it has a place to put your feet in the front and handles on the side. You wouldn't pedal to go you would swivel back and forth and it would get going pretty fast. Anyway my sons birthday is this friday and I HAVE BEEN SEARCHING EVERYWHERE. People think I'm crazy..lol. There has to be someone who knows what I'm talking about..lol. If you could send a link or even the name of it I would be soooo happy. THANKS GUYS!
