Mildura Weekly : Friday January 19 Vol 12 No 11
NEWS 17 FRIDAY, JANUARY 19, 2018 MILDURAWEEKLY.COM.AU A SUMMER classroom filled with eager children and adults listened intently to their lecturer as she ex- plained how the colourful cardboard triangles, prepared for the exercise that lay ahead of them, would even- tually be glued together to form a geometric dome. This was the scene at the ‘geode- sic dome’ building workshop, con- ducted by artist and La Trobe Uni- versity’ Mildura Visual Arts Lecturer, Dr Kylie Banyard, at the Mildura Arts Centre on Wednesday as part of its school holiday program. The Art Centre’s Gallery Pro- grams Officer, Luci Marcuzzo, said the program was something new, and had attracted a mix of people ranging in age from nine years and upwards. “We have a lot of school-aged children, some of whom are here with their parents, and many of them have participated in other ac- tivities that we have run in the past,” Ms Marcuzzo said. “It’s a great workshop, which apart from being a lot of fun, is also very instructive, with participants learning how to construct some- thing, and at the same time they are gaining an understanding of geom- etry. “The centre conducts a number of holiday-based activities and we like to mix the topics up a bit and Kylie had expressed interest in doing a workshop around the construction of a ‘tabletop’ geodesic dome, and we thought that was a really creative idea.” A geodesic dome is a hemispheri- cal thin-shell structure (lattice-shell) based on a geodesic polyhedron! That’s the technical definition of a multi-triangle dome structure. The triangular elements of the dome are structurally rigid and dis- tribute the structural stress through- out the structure, making geodesic domes able to withstand very heavy loads for their size. Large scale versions are built and sold commercially for a variety of uses, including transparent hot- houses. “My first experience of making the domes was using the same co- loured cardboard triangles we are using in today’s workshop, which formed part of an exhibition, and as the years have gone by, I have gradu- ated to making larger more complex versions,” Dr Banyard said. Dr Banyard recently displayed some of her paintings at an exhibi- tion at the Arts Centre, one of which showed a group of art students mak- ing a geodesic form similar to a dome, but made on a larger scale, using a variety of different materials. “I’ve made a large three metre dome out of timber, which you could actually go inside, and in fact there are many like that which people use for all sorts of things,” she said. “I ran a few similar workshops when I was living in NSW, usually with adults, so having the opportu- nity to have the kids here today is something new, and so it’s going to be interesting to see how they go.” Dr Banyard said some of her paintings are of archival images of the 1970s, a time when a lot of peo- ple were building domes to live in, particularly the ‘hippies’. “That led me to want to know how domes worked, and to learn about the architecture, and I found a tutorial on the topic on YouTube, which taught you how to make pa- per domes like the ones we are mak- ing here today,” she said. “I then started creating models of domes in order to have something to paint from, and then ended up exhibiting the models as sculptures, along with the paintings.” The first task set for workshop participants was to ‘score’ a fold along each side of the cut-out card- board triangles, following which they had to be glued together to form a pentagonal (five-sided) ‘can- opy-like’ component of the dome. The process is then duplicated eight times and then each of the five- triangle components are combined to form the dome. “It will be interesting to see how they go, they all seem to have differ- ent ways of approaching it,” Dr Ban- yard said. “The more patient ones will find this easy, it’s a challenge scoring and gluing 120 sides of the 40 triangles they are using to com- plete their domes, but they’re having fun.” More than 25 people attended the workshop which ran for two hours, just enough time for the domes to be completed... well al- most!
