Had an email from “Origami Bob” Voelker (is that like “Maximum Bob”?) with a photo which made me smile – he wrote “I thought you might like to see this photo. Some friends and I made 10 jumbo rhombic dodecs. The 12 faces are printed with the 12 steps of Alcoholics Anonymous, to use as table centerpieces at an annual dinner. Your work has far-reaching benefits!”
It’s good to see A4 paper can be found in the States – they really should adopt it as a standard. I created this over 20 years ago and am constantly amazed how well it was lasted as a design. Oh yes, there are diagrams for the unit elsewhere on this site.
