Back in April 2015 Genii ran an article by John Gaughan on a chamber illusion called "Spirito". While the article has a fair description of how the illusion worked I've been wondering if there is a way to find or purchase plans for it without having to purchase Carl Owen's 'Keep the Wheels Turning: Vol 2'. I've found the book from several booksellers online but I'll never be able to justify the $200+ price tag to my better half.

I'm sure with a bit of reverse engineering from Gaughan's article I could probably recreate it with some (read: a lot) of trial and error but finding blueprints or plans would probably be the least headache inducing.

I'm wondering if there's anyone that can help me?
