Kids who grew up with a healthy love of robots, particularly the Transformers, most likely thought about what a real life vehicle would look like transforming just like their favorite robo-former toy.
One particularly cool example of a vehicle that never got the Transformers treatment is the Bagger 288 excavator, one of the largest vehicles of its kind in the world.
Animator Dan DeEntremont couldn't pass up the opportunity to turn the Bagger into a dream come true for robo-obsessed kids, using his considerable 3D modeling and animation skills to bring the Bagger's transformation to life in full detail.
