END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

it was a great time but no longer maintainable by c.Kleinhuis contact him for any data retrieval,
thanks and see you perhaps in 10 years again

Description: Fragmentarium- Created using pupukuusikko's sweet mandelcup frag  
Code:
// Created: Fri Dec 23 23:05:00 2016
/* A Mandelcup fractal by Pupukuusikko
 
Result of random tinkering with Tglad's Tetrahedral and Dihedral fold fractals,
introduced in http://www.fractalforums.com/the-3d-mandleblulb/2d-conformal-formula-suggestion/

Script is based on Knighty's tetrahedral implementation with Tglad's DE addition from the same source
