Jon Chandler
Chandler has made a very bizarre comic strip "Battle Of The Planets" which is filled with many strange looking characters getting into very strange adventures. The costumed character with the pointed nose and ears brings to mind an art brut version of Maurice Sendak. Really amazing work.

Eleanor Spiess Ferris
This gallery contains a selection of surreal paintings, many of which seem partly influenced by Remedios Varo.

Edik Katykhin
Here's a Russian artist with a lot of insane clay sculptures and peculiar drawings.

These these and these are some of my favorite drawings on there.

And if you enjoy this stuff, I'd suggest downloading all of these pdf files they've made available filled with their artwork.

Piotr Marek
Marek was a Polish artist who died at the early age of 34 in 1985. His paintings are filled with hauntingly surreal environments with figures who's anatomies are often blended into the landscapes. One painting shows an eye socket as a glowing entrance to a cave. The paintings are very powerful and come across as drug induced nightmares.

You can see additional work by Marek such as drawings of his at this gallery.

Dennis Worden
Lots of weird comics and art, some of which has been painted on mousetraps. You're going to have to go here to see the best selection of his work.

My favorite works of his are the selection of pencil drawings he's made of odd characters.

Szymon Kruczek
This gallery contains a good selection of peculiar drawings with an emphasis on weird beasts. The site isn't in english but is simple enough to navigate through using the picture links.
