Wheel Mouse is a project by dark fantasy author Mark Lawrence. Only, Wheel Mouse is cute, and raising money for children with life limiting and terminal conditions.
Tom has done a Wheel Mouse fan art, which you can see here – http://www.copperage.deviantart.com/#/d53bda7 (didn’t want to post it here as it might confude the webcomic!) Tom will be donating the original to help with the fundraising.
