# Sonobe Module

Instuctions for making this model
Below is the Sonobe unit, designed by Mitsonobu Sonobe,
which I learned from Kazuyo Inoue. Above is the capped
icosahedron which she made for me from this unit; you need to make about
30 units for this, but you only need six if you want to make a cube.

Since this must be
very well known, I'm only putting a very brief picture of how to make it.
The second line of instructions gives a little more detail for the last step.

Just in case you want more details than above, you can find some
more diagams here and here. For the model pictured above,
you need to make 30 units. Start off by putting groups of three together
to make the "bumps"; then work out how to put 5 "bumps" together, and so on.

Kazuyo first showed me a kind of stellated icosohedron made
from this unit; and there are
lots more things to be made from it. I've been playing with working
out what kinds of nice ways are there to arrange coloured peices to
make the stellated icosphedron; eg, if I take six different colours of
paper, what kinds of nice ways can I use them to get patterns with
lots of symmetry?
