Golden Mean Calipers

I saw this today on Kevin Kelly's Cool Tools and knew I had to share it. The Golden Mean is a mathematical ratio (1:1.6180339887498948482... also known as the Golden Section) that is seen over and over in nature and is considered aesthetically beautiful. It has been used in art and architecture for thousands of years. Now you can buy a set of calipers for any work you might be involved in that requires the Golden Mean.

Although there are several sources for these tools, perhaps the most elegant and beautiful set is available from Nick Taylor in New Zealand. A bit pricey, but are they ever gorgeous. Here's video of Nick and his calipers. Here's a link to his website. He also takes Bitcoin.
