At the
University
of Seville
in October 2008, I organized this CD sculpture constructon.
The hanging one is finished, but we lacked parts to finish the second
one, on the floor.
The participants first made sketches of the truncated icosahedron.
Then CDs are connected together using cable ties, following the pattern
in the drawing.
Each assembly corresponds to one pentagon of a truncated icosahedron.
The modules are joined together, using additional CDs as edges and
suspended on string.
We had enough participants to assemble two constructions in parallel.
When done, the angles can be adjusted to make the polygons more regular.
We hung one up in a stairwell. Instructions are online
here.
The event was written up in Spanish blogs
here,
here, and
here.
There are more photos on Flicker
here,
here,
and
here.
I also brought some puzzles. Above are screw-together polyhedra,
described
here and
here.
This is a paper puzzle with twenty pieces. It is pretty tricky to
assemble. See
here
Figure 3.
And here is a paper puzzle design with twelve parts.
Above is the solution. It is a paper version of
this puzzle.
And here is a completed paper puzzle with thirty parts, described
here.
