I can name a couple. Both from Norway, both a joy to work with.

Ole Martin Kristiansen: http://piraja.no

Does outstanding work, plain and simple. I'm a Django developer, and I've worked with him on a couple of projects. Without prior knowledge to the way Django templates work, he was able to pick up very fast. Has good knowledge of Wordpress. (Full disclosure: I developed the system behind that site)

Simon Bognø: http://simonsays.no

As you can see on his site, I've already made a public recommendation. :-) Fantastic fellow, also does tremendous work. Has good knowledge of Wordpress, and was able to get an understanding of Django's templates quickly.

I don't really do a lot in the Rails space, so I can't tell you if they're a great fit there… But all in all I'd say they're great designers, and more important, great people to work with.

Edit:

Oh, and Jesse Bennett-Chamberlain of http://31three.com markets himself as a person who provides "Creative services for the design-challenged developer". Never talked to the guy, though.
