Blue Canary Night Light - Obscure? Yes, but, if you're in the market for a nightlight, and you have an affinity for blue canaries, this site has the product for you! You will receive a 10% discount when using Bitcoin, of course. These lights use $0.25 worth of electricity per year, which is the equivalent to the cost of expeditiously sending $27 million worth of Bitcoins to any location on Earth, 14 times over. Just saying.
Nerd Merit Badges - Now offering the "Bought This Bitcoins Badge With Bitcoins" badge for 1 BTC. I recommend also getting the "laptop sash" for mounting your Nerd Merit Badges, although the picture shows the sash on a MacBookPro, which should disqualify you from being allowed to own such badges. I digress...
Constant Sail - The Pirate and Trading Game - I'm also going to link to a forum topic posted by the owner because the site is currently down while being upgraded to support Bitcoin. Based on the screenshots, it kind of looks like a cross between Ultima Online, Tradewars 2002, and the map screen from Super Mario Brothers. In other words, "awesome!"
Bittit - Warning: Not Safe for Work. If anything, Bittit is an experiment demonstrating the versatility of Bitcoin. As people contribute to a Bitcoin wallet associated with a picture, the resolution of the picture improves. I could see this being a great way for an artist to sell their artwork. There are a lot of possibilities here. Be forewarned, some of the pictures are of an adult nature.
Bitzaar - Bitcoin merchant services. Bitzaar provides payment processing and e-wallet services for merchants, currently supporting WHMCS and OSCommerce. If you don't already have a shopping cart, they provide nine lines of code for you to paste to your website, thus giving you an instant shopping cart.
