there were plenty of great examples of self-similarity in nature in Iceland.
The landscape in Thingvellir was excellent for it – where the North American and European tectonic plates are moving apart at a rate of about 2cm a year. This movement has created a rift valley a couple of miles wide which has filled with water but it’s not one big lake so much as millions of little ones. The solid lava rock is moving all the time and so even small rocks have split creating small rifts. It’s impossible to tell how big a pool or a rock is – the shapes are repeated on different scales. We have put a few photos on flickr as a demonstration.
