Here in Scixel we've just finished a corporative animation for the company Impetux, a Spanish company which develops technology related to optical tweezers.
As usual, the work was 99% Blender, being the rest Gimp, Audacity and LMMS. Hope you like it!
Awesome work, Enrique! I love the molecular level ambiance - DOF and vignette make it very convincing.
