Schlafli Tessellations
are somewhat mundane they do pose a demanding challenge in terms of
'elegant' LOGO procedures. This problem considers the eight
semi-regular tessellations which pose a demanding challenge in
terms of 'elegant' LOGO procedures.
![LOGO Challenge - Tilings](/sites/default/files/styles/medium/public/thumbnails/content-00-11-logo1-icon.gif?itok=w1TnHFOa)
problem
LOGO Challenge - Tilings
Three examples of particular tilings of the plane, namely those
where - NOT all corners of the tile are vertices of the tiling. You
might like to produce an elegant program to replicate one or all of
these.

problem
LOGO Challenge - Triangles-Squares-Stars
Can you recreate these designs? What are the basic units? What
movement is required between each unit? Some elegant use of
procedures will help - variables not essential.
