Update: Iron Man 2 UI & motion graphics, both stills and short movies can be found at Perception:
"Using a combination of the Adobe Creative Suite of products and Maxon's Cinema 4D for 3D animation, Perception put out full 2k renders for what would ultimately be a film output for IMAX presentations and normal theatrical release. All working on the Macintosh platform, Perception's team of designers, compositors, animators and rotoscope artists worked tirelessly to deliver the entire package."
