It should probably be noted somewhere that this is more "papercraft" than "origami", and the thing you download is just the net of the solid, not instructions to make what's in the picture.
replyAlso saddened by the lack of Catalan solids

Some of the platonics have folding instructions not just the papercraft net but yeah I wish some of the more interesting ones had actual instructions for the thing being shown too.

Less than a half dozen of the things on that page have a set of actual origami instructions available. I can completely see missing the few out of all the others because they're the less interesting items on the page.

I looked at the page, and decided I wanted to see how to origami some of the archimedian solids, which are lower down the page. I don't find platonic solids as interesting so I didn't click on them. I saw they existed but you can't see that they have folding instructions unless you click on them

Kusudama is your keyword if you want to learn how to do these :)
replyThe 5 intersecting tetrahedra is particularly cool, and I've used these instructions to assemble it http://origametry.net/fit.html

At the danger of spamming this (well - posting it for the second time in 6 months) - I'm still trying to find the select demographic who appreciate this:

Maybe I'm just the wrong demographic, but I clicked around for a bit and couldn't really tell what I was looking at. In particular I couldn't figure out how to "Choose a preset or click Random".
replyEdit: I found the presets in the end, I was not expecting them to be above the other controls, when it's at step 3 in the "getting started" list.

Yeah - the lack of hand holding is partly laziness and partly intentional. I personally love digging into deep visual toys and figuring out what various button presses do.
replyBut I probably do need to make it a little less mysterious and fix some of the obvious ux gotchas.
The brief tutorial is also probably slightly out of date since I added some features.

I was lucky enough to meet the guy behind mathigon for dinner a long time ago. He's brilliant! I'm always excited to see what he is up to! Glad to see this voted up.
