I want to ask permission to fold this model, the thing is that one source tells me it's a traditional model, another tells me it's by Miyuki Kawamura, and one more shows me a variation and tells me that the original version was by Robert Neal.
Who should I contact for authorization then? Here are the links: Traditional: http://www.origami-instructions.com/easy-origami-modular-spinner.html By Miyuki Kawamura: http://gurmeet.net/origami/octahedral-skeleton/ By Robert Neal: http://origamist.de/pdf/24/octahedron1.pdf On a related note, each one gives me a different name. Which is the real one? Thank you guys!
