New Hobby - Escher

This rather wobbly picture is an example of my new hobby. Sometimes my hobbies even last a whole week! But I thought I would have a go at drawing the sort of pictures that Escher drew - the sort that confuse the eye. So I have started by drawing boxes - I copied it from a detail of a larger picture.
This 'hobby' has the advantages that I can do it at college, I can do it when I haven't had enough sleep and can't study properly and it suits the anarchical frame of mind that I find myself in quite often at the moment!
