I have no earthly idea who sent me this extraordinary mug. When it arrived today, I thought for a second, "Gosh, that stained glass pattern looks an awful lot like one of Tom Phillips' thin section micrographs." Upon closer inspection? It was!

I was so delighted that I immediately brewed up some Rooibos and, well, it was out of this world.

Thank you so much anonymous redditor! You made this space geek very happy today.
