The iconic image of MC Escher's Reptiles lithograph from 1943 has become part of a global cultural legacy. This is particularly true in the technology world where it not only explores tessellations in Mathematics, but also dabbles in a playful absurdity. As much as these Reptiles have become a part of our banal lexicon of imagery, few really know much about the history and significance of the piece. I hope this little Ponga linkathon will be as much fun to explore as it was to stitch together.
