Phyllotaxy

This program arranges a series of circular sprites in a pattern resembling a daisy or sunflower.

The sprites are arranged in a logarithmic spiral involving the golden ratio - similar to plant phyllotaxy. This gives us an optimal distribution for the sprites, and makes for interesting patterns.

The color of each sprite is determined by a cyclic function involving time and the sprite's polar coordinates [d,a]. (its Distance from the center, and its Angle around the circle).

When animated, sine waves are used to affect the:

• number of 'spokes' in the pattern (it's radial frequency)
• degree of twist
• color palette used
