Maybe some of these?

• LiveCoin https://bitcointalk.org/index.php?topic=406095.0
• BatCoin https://bitcointalk.org/index.php?topic=400753.0 (legal issues, batman? also looks like the chain is screwed and dev doesn't know how to fix)
• UFOCoin https://bitcointalk.org/index.php?topic=399937.0
• AlienCoin https://bitcointalk.org/index.php?topic=407460.0
• FckBanksCoin https://bitcointalk.org/index.php?topic=407447.0
• PXLCoin https://bitcointalk.org/index.php?topic=418088.0 - I think this is one that would benefit from an exchange the most so the ones who want to invest in pixels at http://pxlcoin.com/ would have a chance to buy them.
