I can’t believe I haven’t mentioned Alex Ries yet! He’s an Australian concept artist. You can find his website here and his DeviantArt profile here. His online galleries are chock-full of gorgeous images of a fictitious alien race he’s invented, the Birrin (shown above). He’s really gone all-out in imagining how this race might live, what their social structure would be like, what they do for fun and leisure (given their unusual bodies), and what their war machines and aircraft and technological development might be like. It’s fascinating stuff. Don’t click over there unless you’ve got a few hours to spend rifling through his galleries.
