At the 2005 Art
and Math Conference
, in Boulder, Colorado, many of the participants
worked together to assemble a big beautiful Zometool
model. This construction is 2 meters in diameter and made from
small plastic parts.
This is a 3D shadow of a uniform four-dimensional
polytope, sometimes known as the runci-truncated
, consisting of 120 truncated dodecahedra, 600
1200 triangular prisms, and 720 decagonal prisms. But
you don't have to understand what that means
in order to appreciate it.
Many people worked together during a
lunch break making modules.
We had to make 75 modules in five
different shapes. Each module is a kind of squished truncated
Most of the modules are larger than
a watermelon, but some are
(We didn't actually finish the last
few of the flat ones during the
We assembled the modules together with decagonal prisms, starting at
Adding modules, it grew quite quickly.
We barely stopped for lunch...
The topmost cell was tricky to attach.
A big thank you to everyone who
helped! This shot shows some of the people present at the end.
The group who spent several hours completing it included Helmer
Aslaksen, Doug Dunham, Tomas Garcia-Salgado, Paul Hildebrandt, Chris
Kling, Francisco Lara-Dammer, Kaz Maslanka, Doug McKenna, Tony
Phillips, and Scott Vorthmann.
Thank you to Carla Farsi for arranging the conference events,
and to Zometool
for loaning the parts for this event.
We started in a rush, and I chose this model to make on the spur of the
moment, so I didn't realize until later that this is the same polytope
I made a year earlier as part of a museum
exhibit in Taiwan
