The obvious tiling properties of the pentominoes may be well
known to many of you but the following may not be.

Consider the tessellation of the 'T' shaped pentomino. Using a
duplicate of it, begin to 'overlay' the two tessellations to
produce interesting tiling effects.

Find the effect that pleases you most and try to replicate it
using LOGO commands in an elegant procedure.

Alternatively you may want to investigate:

other pentominoes;

other overlays;

a mixture of overlays.
