Comic:Dog the Spot

From CGWiki

Dog the Spot is a comic strip originally created in 1989 for an arts magazine by Dudley Horque. The strip is quite unlike Dudley's other work, as it doesn't contain any characters as such, just a blot. However, after a bout of eye surgery, Dudley found himself less capable of illustrating than he used to be, and Dog the Spot made a comeback in 2006.
