DrDude NL made a detailed animation of how to assemble his custom Lego Pneumatic Engine “Simple V6” – his most popular model – in Blender. He began this project in Blender version 2.66 but continuedly updated all the way to 2.72b. Rendering it all in the Blender Internal renderer took him a bit over a day. The entire process took him about a year of on-and-off work.
For more information about this project, see the description on the YouTube page.

aaah, why did you not do the engine animation as apposed to the exploded view being put together?
Well done.
