STEAM is a sculpture that I designed to
be assembled by a group of students at Brown
University. It is made of sixty laser-cut birch
plywood components and is about thirty inches in
diameter. The term
STEAM stands for Science,
Technology, Engineering, Art, and Mathematics, all of which
are involved in the design of the sculpture.
Here is the start of the construction,
on the afternoon of March 6, 2014. We're working
in the
Brown
Design Workshop. Three wooden components at
a time are joined together to make twenty spiral
modules. They are held together with both wood
glue and cable ties. Then we put them aside for a
while to allow the glue to dry.
Next, the first five modules are assembled together into a
larger structure. We are working in the air, with five
people holding the modules and five others standing between
them, making the connections.
I decorated the pieces with randomly generated laser-etched
Voronoi patterns. Each part has four small rectangular
holes where it joins to four neighbors with cable
ties. The mating edges are beveled, so there is some
face-to-face contact area where the glue is applied. They
are finished with two coats of tung oil.
Using both glue and cable ties makes for a very rigid
structure yet it can be built fairly quickly with a group of
people working in parallel. It is intricate but highly
regular, so the same types of connections are made all
around in many places. The cable ties hold the parts
together while the glue is drying and adapt automatically to
the angles between the planes.
After the first ten modules are connected together, we can
turn it over and rest it on the end of a work bench.
It is half complete at this point, but still tricky to
finish.
Many people can address it from all sides as they figure out
where to place additional modules. Each joint is glued
as the structure grows. Because of the many overs and
unders, it is a challenging 3D jig-saw puzzle, even though
all the parts are the same shape.
When all the parts are in place, we used wire clippers to
cut the protruding ends of the cable ties, leaving a nicely
finished appearance. Again, it has to sit for a while
for the glue to dry.
The result is very rigid, with a light, open feeling,
simultaneously geometric and organic. When seen in
person, many people observe its inner and outer layers and
think at first that it is two disconnected structures.
But because the layers connect alternately in cycles of five
(and five is an odd number) a little study shows that it is
all one connected component.
Later, the building folks hung it up high in the entryway
of the Barus-Holley Engineering and Physics Building.
If you're ever in Providence, RI, go
visit it and try to make sense of its unique
structure. I hope you enjoy it!

Thank you to all the students who participated in the
assembly event, especially Lukas Winklerprins, who took care
of many arrangements. Thank you also to Elizabeth
Love, who took many of the above photos.
