I started to create this scene a few months ago and continue to work on it whenever I have a bit of time for it. It's a kind of a science-fiction laboratory for testsubjects. So here are some preview-pics in grayscale with some materials assigned.
This wagon is part of a personal project im currently working on (see "Work in Progress"-categorie). It was build in Maya and rendered with mental-ray and the mia-material. The tools are some surgery-tools and other stuff. Reference for them was Dexters toolkit.
