Fractal generated from tangent circles
The primitive integral Apollonian gaskets from Wikipedia. Picking one fills in curvatures 1–4 below.
Accepts numbers or named constants.
1–3 accept integers, decimals, fractions (4/3), mixed numbers (1+1/3), or named constants (phi, pi, e, tau, sqrt2, silver, plastic). 4 is generated automatically once you leave a field -- and yes, sometimes it just won't work...
(for the math nerds!)
Fine = more, smaller circles. Coarse = fewer, bigger circles -- make stroke widths below smaller if less than .5
