'Emperial'

A graphic design series created from a set of rules:
There must be 20 different pieces.
There can only be 17 white lines on each piece.
There can only be up to 3 circles on each piece.
There must be one orange circle on each piece.
There can only be one black triangle on each piece.
The background must be the same color on all pieces.
There must be a title that reflects the pieces in their entirety.

The finished series consisted of each piece as a 20*20 cm tile on strong cardboard. The pieces would work as wall decoration both individually or grouped together in any order or number likable.
