Description

Turtle monad and monad transformer.

The Turtle monad embodies the LOGO style of imperative drawing - sending commands to update the a cursor.

While Wumpus generally aims for a more compositional, "coordinate-free" style of drawing, some types of diagram are more easily expressed in the LOGO style.
