I like to think that my brain has two sides: nothing so simple as a left side and a right side, but two very different sides. In the brain department.

I could be wrong. But if you have a look at the art at The Celtic Art Works and Retropolis you may - at least - consider that I could be right. And while you're making up your mind about that I'm going to sneak up behind you, pick you up and turn you over, and then try to shake all the change out of your pockets by tempting you with the t-shirts, posters, coffee mugs and other odds and ends that I offer here for sale.

I know, I know. It's intrusive. But look at all that stuff.

Whether you want to find out just how mad the science of Retropolis is, or to get a collection of original Celtic knotwork designs to use in your own projects - or even if you want to page through an interactive tale about rocket ships, the Space Patrol, and brains in jars - you can find what you're looking for at Thrilling Tales of the Downright Unusual and The Retropolis Bookstore.

If you drop by the Thrilling Tales site, you really ought to schedule stops at the Title-O-Tron and the Pulp-O-Mizer.

Here are some curated collections of T-shirts, posters, coffee mugs and other products: they offer work that's not - or mostly not - by me, but if you like what I do then there's a pretty good chance you'll find something to like here, too.
