Origami designer Fergus Curry shared with me the diagrams for his Rhombic Triacontahedon, I was determined to give it a try:

30 squares in 5 colours, some clever unit folding later and I had the bits needed to construct this little gem. A positive tab-pocket mechanism, some strategic placement of colours and pretty soon you have a lovely sphere made of rhombi. [edit]: A friend (JZag) pointed out this is a D30 (DnD reference there) – nice and nerdy.

The lock is positive and for the most part pretty easy, the last few are really challenge as you lose the ability to shimmy the model from the inside, but with some gentle massaging and the last unit finds it’s place by itself.

There is lots to like in this model – the folding scheme is sensible and fairly easy to achieve accurately, the construction is satisfying and the colour distribution looks fabulous.
