Well, not yet, but at the school I work at, I've been recruited to do various stages of design on different classes' banners for the upcoming Sports Day.
So, here's my designs for 6 Escher (the classes are named after artists). The fishes are tessellating patterns, based on much simplified versions of some of Escher prints, which allowed the children in the class to do their own motif to the Mobius strip I designed as the central piece, again, based on another of Escher's prints.
I'll stick a few more up (I've now done 5 different banners), as I get pictures of them.
