Great pictures, Chip! Here's some pictures of mine, first with some pictures of an asamushi from the OTTI 7/8:
Then a picture of how it looked after that asamushi (only 4 steeps). Wow!
And finally, I was drinking a fukamushi today and noticed that the fine powder had gathered not unlike the way the sand gathers on the ocean floor. And with the crackling visible as well, I thought it was like a fukamushi ocean! The color didn't turn out so well on it, though.
It's a great cup!
