Pseudo-ascii-art kaleidoscope

Made with Blender 2.82a
Rendered with Cycles

I used CGMatter’s ascii-art shader (here is his tutorial) but I changed the 6 asciis with 64 different-sized squares.
I know I could have the same result using instancing and the Edit Vertex Weight modifier, but I just wanted to try not just to use the shader but to change it in some ways.
