The electra icosidodecahedron, created by David Mitchell, is made up of 30 electra modules, a relatively easy module to make.

I made them with green and yellow squares of 5 inches each. The band of yellow running between the green is something that I saw in one of the videos on origaminut and I have been thinking of implementing it in one of my ornaments ever since. So here I finally got the chance to do it.

The curler units by Herman Van Goubergen are deceptively easy to make. In fact the basic units are easy to make since they involve creating a water bomb base and curling the 4 arms towards the centre. But putting them together into a ball takes time.

The curler units can be assembled into different spherical structures. A cuboctahedron (12 units), a rhombiccuboctahedron (24 units), an icosidodecahedron (30 units) are various structures that can be made from the curler units.

What I have tried out is the Icosidodecahedron, made of 30 units i.e., 12 pentagons and 20 triangles. Each pentagon is surrounded by 5 triangles and each triangle by 3 pentagons.

The curler unit assembly looks good whether it is done in a single colour or in an abundance of colours. I did mine with a mix of colours. I got bits of all possible colours that I have with me and made my curler units. And I really liked the colourful end result :)
