The map of Milan on a Moebius strip
A step of the deformation that transforms a map of Milan of the sixteenth century (which is roughly a decagon) into a Moebius strip. This is obtained by identifying two sides as indicated by the blue points. You can see the preceeding step; here you have to identify the two shortest sides with a torsion to get the Moebius strip.
