I've been selling scripts on CodeCanyon (http://codecanyon.net?ref=fillerspace http://codecanyon.net?ref=fillerspace). I spent a day or two on each of 3 plugins (2 jQuery, 1 WordPress) back in May, and they have earned me $306.50. Not exactly retirement money, but some of the top sellers make 5 figures per month. This is truly passive for me since I wrote the code once and haven't had to do anything since.
