CAUTION: this script and variations of it can lock up some PCs and have been known to corrupt some PC users' WebTV viewers. I recommend that any pages created with this script be .htaccess for MSNTV IPs only.

THE SCRIPT

NOTES:

Start with reference position. I have used 272 pixels of left offset and 185 pixels of top offset. This centers the animation on the WebTV screen.

Define parameters.
n = part of your number for the radius.

r++ increases value of r by 1 each repeat.
r-- will subtract 1 with each repeat.

You can use sin or cos trig functions .. if both are the same and all other numbers are the same, you will make a spiral. I do not recommend the use of tangent, cotangent, secant or cosecant trig functions.

The % number controls 'tightness' on turns. Bigger number makes the outer turns group more closely.

You can get all sorts of shapes and patterns by adjusting any of the numbers and changing the trig functions. If you start with large n and r, use -r*Math.sin(n/#); and let it work its way in..

The last line contains your stopping point and the speed control. In this example, as long as n is less than or equal to 4096 the script repeats itself every 20 milliseconds.
