### Colouring Patterns

When you have been sitting at a computer display for a long time, you become
stiff and need to relax well away from electronic systems. An ideal way to
do this is to print out a pattern and then colour it in using crayons, felt
tip pens, or water colours.

A sample set of polyhedral patterns is listed below, they have been
made using the RISCOS program, "!PolySymm" mostly using the "wire" display
option coloured black so that both the front and back can be seen at the
same time.

Each pattern is a Drawfile which has a shaded 3D model of the polyhedron at top left,

a name in the centre and a line drawing of the pattern below.

RISCOS users can unpack the Drawfiles from the file patterns.zip, which also has instructions for how to make your own.

Users of other systems can find them in the file patterns.pdf

The list below describes the patterns we have made so far:

**C001** Truncated icosahedron seen along a 5 fold axis
**C002** Truncated icosahedron seen along a 3 fold axis
**C003** Truncated icosahedron seen along a 2 fold axis rotated a little
**C004** great icosahedron seen along a 5 fold axis front and back
**C005** great icosahedron seen along a 5 fold axis just front
**C006** great icosahedron seen along a 3 fold axis just front
**C007** great icosahedron seen along a 3 fold axis front and back
**C008** pentakis dodecahedron seen along a 5 fold axis
**C009** pentakis dodecahedron seen along a 3 fold axis
**C010** Truncated icosahedron ( not stanard faces) seen along a 3 fold axis
**C011** Truncated icosahedron ( not stanard faces) seen along a 5 fold axis
- 23rd stellation of the Icosahedron
**C012** seen along a 3 fold symmetry front and back
**C013** seen along a 5 fold symmetry front and back
**C014** seen along a 3 fold symmetry front

- Compound of 5 cubes
**C015** seen along a 5 fold symmetry
**C016** seen along a 3 fold symmetry
**C017** seen along a 3 fold symmetry just front

**C018** great stellated dodecahedron 5 fold symmetry
**C019** small stellated dodecahedron 5 fold symmetry
**C020** snub cube seen along a 4 fold symmetry

There is also a Drawfile, "Nets", which contains 2 coloured nets which can
be cut out and used to make into 3D models for patterns C001 and C020, so
that you can find the viewpoints from which the patterns are seen.
