I think this has the potential to be my favorite thread on this forum! Absolutely love celadon.
I recently posted some pictures of a supposedly old (sold as 19th century; doubt it's true) celadon cup quite similar to those in the pictures posted by brandon. I won't double post, but if you're interested, you can see it at viewtopic.php?f=36&t=13403&start=135#p165259
I might also have taken some pictures of some celadon pieces at the Shanghai Museum when I visited last year. I'll see if I can dig some up later this week.
I also really liked some modern "Koryo" celadon teaware and incense burners I saw in Korea but they were unfortunately out of my price range at the time. (That just means they're still there as an excuse to go back when I have more money, though.
