I assume this is partly interesting/funny because in the UK, both "Iceland" and "Spar" are grocery store chains :)
I've always wanted to build a birefringent sun dial, "I only count the cloudy hours": https://en.wikipedia.org/wiki/Iceland_spar#Uses
That's very cool. I wanna get one for myself
Huh, it's actually on Amazon for something like $8 for a small piece (no idea if they are fakes though)
Now I'm tempted as well...
