We found this over at Uncommon Goods, and we'd love to see it in use, full of colorful fish. The two-handled shape reminds us of a Victorian punchbowl, and it in fact could be used as one, or as a vase, or for storage.
In fact, we're not quite sure why Uncommon Goods landed on fishbowl as its first use. The glass is slightly greenish (from the anti-glare treatment for its original function) and just under a foot tall and wide. $65 here.
