I am getting really excited over how fast progress is made just a couple of days from project restart. The strange thing is that what takes most time is to build the models for the scenes. Animation is relatively quickly done. Datsville as scenery (...) (19 years ago, 30-Sep-05, to lugnet.cad.ray, lugnet.animation)

Ok. So this is exactly the reason I didn't want anyone to invent a new animation scripting language for Legos!
