1058: Twister A

Clocking on for another round of procrastigami, I decided to give the first of the “twister” series a go:

This is “Twister A”, designed by Ilan Garibi, a lovely dimensional fold with a final twist to finish it off.

I have folded a few square twists, this one perches a twist on top of the intersection of opposing ridges, contains remarkably few folds on top of the base square grid.

The basic molecule tiles awkwardly – because of the directionality (it forms in a clockwise direction) of the molecule, you have to reverse adjacent molecules if you want them to line up.

You can tile them, twisting the same direction, but you have to offset them so they are not lining up – I think this looks less tidy, so decided not to fold this, opting for the reverse solution.

The actual twist on a single molecule is relatively manageable if you flatten one of the ridges – it sort of then all happens at once. Lots on the same sheet is problematic – the ones accessible around the edge follow the same conventions as a single molecule. Internal molecules are much harder to twist – I can imagine how untidy it would be on a large sheet.
