More variations from Fractal Lab, a shader based real time 3D fractal generator.
The central motif in this structure is based on a 5 fold symmetry, creating 10 identical "pie" slices, which reflect kaleidoscopically. But looking further you see that each of the 10 "pores" surrounding the orange center is another kaleidoscope center, and that the space is subdivided by rings of smaller pentagons, placed in pairs on the sides of their parent pentagon. [And with all these pentagons floating around, these motifs have strong visual relationships with Penrose tilings . . .]
But what really interests me is the complexity of the boundary where the simple planar structure breaks up and turns into 3 dimensions [it will help to run the program to see this]
