Ahoy, Ariadne! Something for Theseus!

Glanced very quickly at this and was reminded (after looking at the diagram) of a primary school 'project' linking Maths with Art! We called it the golden rectangle......
We also had fun changing cuboids into cubes (thanks to my collection of M&S individual filter coffee boxes, which happen to have square bases!)
Apologies to thatbags and Theseus for lowering the tone

I tried to get my head round some of it too, and will have to try again!!

Theseus says thank you, and to tell you he is still trying to get his head round some of it, but it is very interesting.

Thank you! I have sent him the link. Didn't actually read it; looked at it, thought how clever you both are, and sent it on.
