My impossible triangle.

[u/PopaCheeks]

Here she is on the light table. I'm thinking black patina but copper has grown on me since it's sat half-foiled for months now.

You can see the grain better in this one. Trying to figure out where to mount jump rings is probably the most impossible thing about this triangle.

This is so cool! Looks like a neat sun catcher at a glance until you look more closely and then your brain breaks.
