stained glass triakis icosahedron
It was hand-made from cut glass (score and snap), bound in copper foil (rather than lead came), and soldered with 60/40 (tin/lead) solder.The lighting is provided by strip of LED lights - it consumes little power, and could be supplied by a wall adapter or computer’s USB port.I find the shape to be both aesthetically and mathematically pleasing.First make a a lot of uniform isosceles triangles (at least 60, probably more if any turn out badly). I made mine about 2.5 inches tall and 1.5 inches wide (a very poor-man's golden ratio).
On the Making
- Bind all their edges in copper foil tape, solder the borders
- Solder them all together so internal dihedral angles are all exactly 138.189685°
- I made a little jig out of coat hangers and hot glue to help get the angles right.
- Before closing it up, shove an LED light strip in there.
