well...if you can walk forwards and backwards spinning should come easily...when you walk you have to shift your weight to one side and pick up your hand. sooo...instead of shifting your weight and moving your hand forward move it in a spinning motion...

...read the turtle guides in this forum...it should help
and it might take some time to build up balance...try shifting your weight a little less or slow down

Vin Diesel and the Internet - relation? I THINK SO
Vin Diesel invented the internet while trying to steal cable TV.
Contrary to popular belief, it was in fact Vin Diesel who invented the internet. Al Gore stole the designs when Vin fell asleep at his keyboard.
