I got back from a trip to Istanbul 10 days ago and I spent a stupid amount of time out there thinking "I could build something like that in Bryce".  I totally fell in love with Sinan's architecture and in particular the Sulamanie Mosque which this is (fairly loosely) based on.  This is a work in progress but if I don't post some of it now I'll rush the end result in order to get it up.

I tend to like building models and then work out where I can put the camera afterwards so the POV for this is likely to change a bit before I've finished.  I started with the whole thing in marble and added the ceiling decoration (it'll change before I've finished as I just wanted to try out some ideas), I am about to start playing with some form of decoration in the second tier of domes and could do with putting some windows in them too.  The whole thing (with the exception of the balconies below the domes) has been built out of Bryce primitives.

When the whole thing is finished I dread to think how long a volumetric render of this is going to take but I want to see light streaming through the windows :)
