By drawing vectors on a tool like Inkscape, we can make a series of commands to a laser cutter to cut the shapes from acrylic, plywood, birch, or MDF. For a while the Tongs have loved the Platonic solids, and much more exciting and beautiful shapes, like the one that User:Pilchard gave a certain mathematician for his birthday.

Acrylic ('Perspex') is cheap, comes in clear colours, and the cutter will cut 1200x900mm. To see what's available, have a look at Hobarts.

What could we make?

Use your favourite image search engine to search for 'IQ Lights'. It's the best math object / lampshade construction system I've found. Does require a material that can bend though, like the thickness of plastic used in milk cartons, or slightly thicker. 0.8mm polypropylene looks ideal. Pilchard (talk) 11:34, 25 January 2018 (UTC)
As a material, polypropylene is not allowed on the laser cutter, except in sheets like the ones you describe, less than 1mm in thickness. Any thicker and it releases toxic chlorine gas, harming both people near the cutter and the laser itself! Hobarts sell it too, so I could add some to my next order.
