Kerrin Hardy is the creator of the Jonathan Coulton Project, sometimes abbreviated to JoCoPro, a Web site and blog created in June 2006, which is dedicated to making and sharing videos for Jonathan Coulton songs. The site features videos by a variety of creators, including Kerrin himself.
Besides his work on the Jonathan Coulton Project, Kerrin used to help maintain Coulton's Web site, and remains one of Coulton's most dedicated fans. When Jonathan and Paul and Storm toured the UK, Kerrin would tour with them, carrying their luggage and merchandise.
Kerrin is currently working on a new project to make a Graphic Adventure Game based on Jonathan's music. The game is entitled Jonathan Coulton Adventures.
