The blog Abduzeedo (http://abduzeedo NULL.com) is more geared for design than comics, but this tidbit spans multiple art mediums. As part of their blog they include Daily Inspiration; a once-a-day collection of strange, creative, or just plain interesting images and videos that help get the creative juices flowing.
You can subscribe to their RSS feed (http://feeds NULL.feedburner NULL.com/abduzeedo) (which will catch all of their posts,) or if you’d like to see just their Daily Inspiration submissions, you can go to http://daily.abduzeedo.com ( http://daily NULL.abduzeedo NULL.com) to see them all on one page.
