Inspired by Charlie's BAM version I started from scratch for QB64 version with added full colorization mode.
Use b key to toggle color modes or esc to quit, any other key shows another random tile tessellated screen:

' But I also wanted to try a colorized version.

' So use b key to toggle between:
' 1. a mod of Charlies version with different pixel block size with black backgrounds
' 2. the colorized version which reminds me of Magic Eye Art
