I'd be interested to see Nick Sayers' playing card cutting plan. You can see from this photo how he's using the playing cards as rhombi:

Yes, I saw that cutting plan. It's not the same as the one Nick Sayers is using though: if you look at his spheres the cards are arranged differently to the makezine sphere. Still very cool though!

George Hart's webpage is brilliant for this sort of construction:

Especially his pages on the 'slide-togethers' which is the approach Nick Sayers is using to approximate the IQ light system.

And of course now I learn that George Hart is Vi Hart's father. This makes complete sense.
