Past Halloween costumes in this family have included Marty McFly and ET, but this year Cooper and Ziggy are dressed as Max and Furiosa from Mad Max, and damn do I want their war rig!

Cooper and Ziggy's parents are both software engineers who have made them this epic war rig out of old PowerWheels cars, cardboard, and a lot of love. The rig comes complete with an iPhone app override that turns it into an RC car.

If you're a fan of their work, the family asks that you make a donation to Cycle Kids, helping children live an active lifestyle.
