Tessellations - Escher Style

Hello, my name is Bruce Bilney. I live in Adelaide, South Australia. I am a semi-retired schoolteacher, sort of inventor, prolific writer of rhyming verse, and I take an interest in Australian native fauna. One of my consuming passions is creating tessellating patterns. I maintain a website called www.ozzigami.com.au. I am pretty passionate about such idiocies as the Iraq war and environment climate-change denial. So-o-o . . . Please contact with thought-through comments. Ta. Bruce
