This is πg he / she is a pig. Some years ago I had the idea to present the whole course with pigs. I'd noticed how much my students liked experimenting with flying pigs so thought I'd milk the idea for all it's worth. I got as far as mechanics then I must've gone climbing or something. Emma and I have just finished the last bits of the student website so with time on my hands I thought I'd pick up the pig.

Here are the latest instalments. I'm particularly pleased with cetripigtail force :-)
