Stained Glass Illusion

I saw this neat optical illlusion done in wood...........I think on Pinterest...........or possibly

I thought it also look neat in stained glass.

It is based on the Penrose Triangle................defined in Wikipedia as..........

The Penrose triangle, also known as the Penrose tribar, or the impossible tribar,[1] is a triangular impossible object, an optical illusion consisting of an object which can be depicted in a perspective drawing, but cannot exist as a solid object. It was first created by the Swedish artist Oscar Reutersvärd in 1934. Independently from Reutersvärd, the psychiatrist Lionel Penrose and his mathematician son Roger Penrose devised and popularized the triangle in the 1950s, describing it as "impossibility in its purest form". It is featured prominently in the works of artist M. C. Escher, whose earlier depictions of impossible objects partly inspired it.

Using Sketchup, I took a shot at coming up with a stained glass version

I did this design a few months ago. Today when I went to build it...............I noticed the red board is much wider than the other 2 I modified the design to make all 3 boards about the same width.

Glass selection

My corners will be Hobby Lobby white, and the borders will be 3/4" Hobby Lobby amber.

The clear glass will be Hobby Lobby ????????

The red, blue, green, are all Hobby Lobby standard colors.

Getting started on building the panel

Panel Foiled, ready to Solder

Zinc Frame

Process Steps Used:

1. On LH side, cut 45 deg on bottom, make top about 2 inches longer than needed
2. On RH side, cut 45 degree on bottom, make top longer also
3. Make bottom piece exact length with 45 degrees on both sides
4. Solder zinc to copper foill spots on panel, solder 4 corners, flip over and solder other side

5. Cut top piece to exact length
6. Use Dremel with cut-off wheel to cut RH and LH to length

7. Solder in both Handy Hangers on top corners, fill exposed top gaps with solder

Closing Thoughts on this Project

The hardest part of this project was getting the drawing right in Sketchup!!

It was relatively easy to build, and it looks nice in the sunlight.
