Atomic Timekeeper

Here's a recent illustration for 5280, Denver's Mile High Magazine, on the local atomic clock at the National Institute of Standards and Technology in Boulder. It's the most accurate in the US but still manages to lose a whopping one second every 300 million years. Sloppy. This was created with some 3d modelling composited with 2d textures in Photoshop. I've included some of the roughs developed en route to the final piece, also visible on my site with related work here.
