I'm probably the Gethan Dick you're looking for - as far as I can tell there aren't any others. I've made this website so that you can find out about my work as a creative educator, get hold of some of my writing and art, see what I'm up to in the War Against Boredom and buy stuff I've made in the shop.
If you wanted something else then maybe I'm not the one you're looking for after all - in that case, best to email gethan.dick at gethan.org and check.
