Demo of Golden Ratio in Artistic Composition (fairly disorganised)

Over the years, I've built up a collection of Golden Ratio Calipers... and I decided it might be quite useful for people if I made a video comparing them. Some of them are really good - some terrible. So I set up my camera... and found that my video-space looked a bit bare... needed a painting. So I decided to…

Golden Ratio Poster

I've been tinkering with movies etc today, and (while I was waiting for things to render) played about with one of the stills and made a poster. I don't know if I'll ever turn it into an actual poster. If anyone is interested though - let me know how big you want it, and I'll do some costings etc. Alternatively,…
