Fractal Flower Mosaics
from the set Fractal Collages, a collection of Digital Visual Mashups
One of a set of mosaics I made from digital photographs of flowers.
The individual tiles are fractals, digital music visualization stills, digital photos of groceries and disco balls, masterpieces of modern art, other psychedelic images, and collages and mosaics of same.
