Is Go equipment in unorthodox colors/materials ...

[Anzu]

Do they make Go equipment in unorthodox colors or out of exotic materials?

I was thinking, maybe a blue board or something. Stones made out of marble or granite?

Bowls made out of metal or stone would look pretty interesting.

Yes.
Everything is possible.
Ranging from simple, raw, self/home made, to exclusive.
I've seen metal and marble boards, glass board, marble bowls, stone crafted bowls, irregular wooden bowls, rocks as stones, jade for stones, cristal floor goban, a lego go set, gem stones (well, actual pictures of it), bottle caps for stones, a board on a blanket and on a rug, etc.

The Nihon Kiin's museum has a solid glass floor-standing goban, weighing 90 kilos, if I recall.

I also brought a 15x15 traveling set with a blue board in Russia, but I can't now find it.

A Japanese woman with eye problems had dark and light green gostones made for her.

Oh, and I've played with paper and colored pencils (trying to avoid ko fights).
