Ooops, should be:
var radius = a * Math.pow( c, angle );
And angle is in radians, so Math.PI * 2 is a full circle. It's what
Math.atan2() gives you (not so incidentally), so if you want to tie it
to a mouse pos...

Hi Jason,
to translate the Wikipedia page:
var c = Math.pow( (1 + Math.sqrt( 5 )) / 2, 2 / Math.PI );
var a = aPositiveRealNumber; // like, 1
// in your loop:
var radius = Math.pow( a * c, angle );
var x = Math.cos( angle ) * radius;
var y = -Math.sin( angle ) * radius;
You keep incrementing an
What is a golden spiral?

"In geometry, a golden spiral is a logarithmic spiral whose growth factor b
is related to φ, the golden ratio. Specifically, a golden spiral gets wider
(or further from its origin) by a factor of φ for every quarter-turn it

Hi,
I think you need to do Rectangular to Polar conversion after working
out your r value based on your angle.
Assuming c is calculated by
c = \varphi ^ \frac{2}{\pi} = 1.358456
Then here is some psuedocode.
for(angle = 0;angle < revolutions;angle += step) {
c = 1.
\I'm no math whiz, does anyone know how I can draw a golden spiral and position
and move sprites/movieClips along a golden spiral path?
