Way back in June last year, I was invited to be a guest speaker at the 37th National Sci-Fi & Fantasy Convention in Wellington. The organisers gave me a 1 hr slot, and wanted me to teach the attendees how to fold one of my models.
Now this presented me with a challenge, in that my models tend to be complex, and often take far longer than an hour to fold, let alone teach to a room full of origami novices!
My solution to this was to teach one of my modular designs - each piece is fairly simple, and with teams of people working together the complete model can be made within the allotted time - but to make an event of it, I decided to go big...
Armed with 16 pre-creased sheets of 75cm square of poster paper, me and the team folded all the necessary modules, and I spent the next two hours carefully assembling all the parts - only to have it collapse in on itself in the final stages!
So I jerry-rigged some internal supports from cardboard tubes and started again, this time taping all the locking folds in place, and finally, just in time to be unveiled at the closing ceremony, BB-8 stood tall under his own weight.
The ball measures 50cm across, and the head is 30cm in diameter, almost 1:1 with the movie prop used during filming
