I've posted a series of images I made into a gallery here on the site. These wall hangings were ultimately printed 10 feet long, so it was a technical challenge to render so large. I used Maxwell Render to get the final output because it will just keep rendering until you're happy with the results.
It was a fun project, both technically and compositionally. Some post-processing was achieved using an app called Flare on the Mac.
