Thank you guys. I think the thing about origami that I find so captivating is the people who actually do the designing. Like your son Don. They take something that's 2 dimensional and create a 3 dimensional figure.
To be clear, all I can do is follow the directions. That takes some time and patience, but the people who actually dream these models up are the real magicians. Folding their diagrams is like hitching a ride on genius. It's a lot of fun.
I'd love to see some of your son's work Don.
