A friend of mine has this beautiful mug. I've always admired it, and I finally found an online retailer (with a little help from another friend): http://www.thedanugallery.com/colmdiris.html
The price is a bit more than I expected, though. I don't think I'll be replacing all our coffee mugs anytime soon...
In my searching, I also found these, which aren't as much fun, but are certainly more affordable.
There's a beautiful pitcher here, but I am trying to decrease my cream pitcher collection at the moment.
