Four rectangles form a square gap in the centre.
ID=03, Version=101, Permutation #01
Each rectangle can take one of 4 colors. For reasons of symmetry, there are then 6 possible arrangements per centre.
With centre black and white, there are a total of 12 motives.
Other patterns: P #02 / #03 / ... / #06
The other patterns can be found using the search function, e.g. "ID=03 | V=101 | Black+White Hole".
Image width in cm: (50 / 100 / 120 / 150)

For now only permutation #01, center black and white.
Other combinations can be created on request and upon request.
