I'm building a website that allows you to enter what you've got in your bar, and get the list of cocktails in a friendly and no-registration-required fashion. Lots of Ajax and JS visual effects.

BTW, I recently started a blog around JavaScript development and Ajax, focusing on examples from my development of this website. Feel free to check it out:
