Squint when looking at that picture zoomed out.........

Probably need some piece of image recognition/matching software to find the actual image or images that were used as the basis for selection of the various pieces but that 'collage' is not random, there is distinctly a seated man with a beard on the right(purple area) and there is probably other stuff going on as well(seems to also be a second larger face in the same area)

Edit: it reminds me of something, of the top of my head the first thing I can think of is a picture of anton lavey.....................
