Before Christmas one of the members of my local camera club did a session on Spirograms. It was a really interesting evening and was something I hadn't attempted before. With a little bit of time on my hands, I decided to give it a try today.
The spirogram was created by hanging an LED torch from rafters in the garage, laying the camera on the ground and pre-focusing on the bulb. Then you swing the torch and photograph the resulting light-trail.
For those interested, settings were 45sec @ f11 ISO100
