Hi Guys.
I got bored yesterday afternoon, and I was looking at circular motion with ActionScript, so I knocked up a poi simulator that interactively allows you to adjust hand and poi rotation around the hand.
Download poi simright click and choose save as - I find the flash player has a much higher frame rate than when the movie is displayed in the window.
I'll probly add another poi and arm, and also strings, and a couple of different trace modes at some stage when I get bored again

patterns you should be familiar with
arm 1 poi 4 - standard flower
arm 1 poi - 3 - antispin flower
if you want to see longer trails just multiply both figures by 2 - eg
arm 2 poi 8 - standard flower double speed double trail length.
