Talk about “life, the universe and everything”, this model is an intriguing exercise in pre-folding:

Organised ridges, counter folds of diagonals and the model seemed to curl in on itself in a magical sort of way. Interestingly it is composed of 42 base pairs – I wonder if that is a coincidence?

Folded from an A4 page, strangely, the resultant model is huge (as the reference stage suggests, but is has an inherent strength and rigidity that I found surprising.
