As part of the Sydney Origami group’s weekly challenge, we were tasked with a modular:
This is Regenbogen, designed by Maria Vahrusheva, described in the following Youtube tutorial video
The units (you need 30 for a ball of this configuration) are quite easy to fold (I managed to teach them to my Pastoral Care group kids – their version of this fold is still a work in progress … yes, I have folded nearly 2 of these now) and luckily (for boys at least) consists of mostly folding in half – something most people can do.
The construction/assembly was interesting, I decided to use a little glue to stabilise the units as they formed a larger and larger structure.
In the end you get a beautiful stellated ball, with some beautiful duo-colour effects. Try this you should.
