Rotated out from the 2D mandelbrot to 3D by Daniel White and Paul nylander: http://www.skytopia.com/project/fractal/mandelbulb.html by the means of hypercomplex mathematics and spherical coordinate magic.
LIfted out to reality by me with the means of DE-render from mandelbulb 3D as voxel-slices, made into vector 3D with Fiji, cleaned up in Meshlab, checked and repaired with Netfabb, sent to shapeways to be printed in stainless steel.
I have several models in different materials in production right now, and my next order will be in silver!
M3D > Fiji > Meshlab > Netfabb > Shapeways > your finger
I JUST LOVE TO WEAR THIS ONE, to feel the weight and structure of the mandelbulb around my finger...
If you need other sizes, just PM me and I will make your size, Measured diameter printed in Stainless steel: 20.3mm
