Yet More Pentominoes

Yet More Pentominos.

These are at least customisable and the script is very compact. Each pentomino is defined by a codeword where the digits 0,1,2,3 are interpreted as unit steps E,N,W,S.

e.g. the cross is defined by the word 030101212323

Some pentominoes are chiral and setting mirror to 1 creates the mirror form.

The script can be adapted to other polyominoes by the addition of their codewords. For example to add a square, use the the codeword 0123
