shpz #43

"shpz" are assembled from different criteria in a graphical fashion.
they differ in complexity can be based on one of three base shapes ("shp" = circle, square and triangle). curated palettes are used to please the eye.
some extra features include rounded ("rndd") that affects squares and "flppd" that turns triangles upside down.
furthermore some tokens can have the mutation parameter called "mttn". it shifts the circles y-position, rotates squares and randomly flips triangles.
