Like most of my best blog ideas this one is completely stolen from a colleague. (He can let me know if he wants credit here for directing me to the widgets). I learned that Wolfram|Alpha has an easy template to allow you to make widgets on their site.
The widget you will see at the bottom of the post was developed from Wolfram|Alpha’s widget developer. It took ten minutes to make including watching the first half of a 7 minute video explaining how to make a widget. At first I was unsure how to start, but after seeing a couple steps on the video I realized that the interface was really easy to use.
