One of my contributions to Troll Bridge (trollbridge.film) was to model the logo.
Here are a few steps showing the process and some detail shots.
Additionally I included some solos of the details added in ZBrush for the displacements.

The entirety of the lettering was modelled in Pixar Subdivs purely in Modo. I painted the materials on in Allegorithmic Substance Painter with materials created in Substance Designer.

I also included a functional demo of the rotary controller I made but we didn't end up using in the final shot.
