Obscura IX,1 by Kwanghun Hyun, made with a Tessar lens
There's not much information at Kwanghun Hyun's webpage for his DIY cameras. Ttechnically, they aren't camera obscuras as he titled them, but who cares? They are mechanically gorgeous! http://www.kwanghun.com/kwanghun/portfolio1.html
Those are stunning! I've been building my own cameras for a couple of years, but never anything as beautiful as those. Mine tend to be made of cardboard and tape.
