Spiral Staircase

This image of recursion is not done in software – it’s an amazing achievement in bricks and mortar (and a beautiful photograph):

Thanks to quapan. It’s presumably his or her foot that can be seen at the bottom of the photo. Nice to see the maker’s mark in the artefact itself.

Have a look at this great Moebius comic strip made by cartoonist and graphic artist Jim Woodring

Below is an animated version of the strip so you can follow the story:

If TLA is a recursive acronym, it must also be allowed that T-shirt is a self-describing word. And just look at this T-shirt:

Inspired by recursion hell, I thought I should have a go at contriving some recursive images of my own. My plan was simple. Surely all I had to do was hook up an external monitor, open the Mac Photo Booth application and place the monitor facing the screen of the laptop. In this way I thought I should able to create an instant Droste effect. But when when I pressed the ‘take photo’ button, all I got was a white screen as if I’d overloaded the system.

In the end I had to resort to the unsatisfactory solution of using a third device, viz my camera. It was difficult to get the two screens parallel while at the same time keeping the camera out of the picture:

This next one was a bit better in terms of the angle but didn’t show the recurring image as well.

At the end of the day, I wonder if I could achieve better results more simply just by using the screen-grab feature.

…I could end up being here all night at this rate.
