Clickwheel.net is a new service where you can download comics to your ipod. My comics have been added to clickwheel, or are in the process of being added. Footprints is up now and I have more to come.
There are plenty of other comics on the site. I don't have an ipod so I can't check out what is offered or see how my comics look on the ipod.
Go check out the site, it's really cool, and it's free.
