Alex Mallinson over at X-bam illustration decided one day to mock that dancing Citroen ad and got busy. In five days he managed to create the bulk of it all, 16 hours of car/robot construction, another 16 hours animating that, 8 hours creating the carpark and then set it to render which took 8 days. So, in less than two weeks he managed to make this film, which mocks the original quite well. (read more for a good laugh and a Quicktime file).
The original Citroen "transform".
