This is aimed primarily at those people who have used LOGO before.

It will be for those people who feel comfortable using 'primitives', those who have possibly compiled procedures and probably produced small programs.

As ever, the challenge will always be to produce elegant solutions to the problems asked. Elegance here implies simplicity. The focus is on rhombii, in particular those formed by butt jointing two equilateral triangles along an edge. Or:

REPEAT 2 [ FD 40 RT 60 FD 40 RT 120]

n.b. In keeping with previous practice all LOGO commands will be in uppercase lettering.

The design below is part of tile seen in a shop - sadly now closed, at King's Cross in London.
