A very creative father (and uncle) who goes by the name Griddlock Cosplay built an absolutely brilliant Mechwarrior costume that requires both a child and an adult in order to make it work. There is a fully functioning fan and Arduino controlled LED lights to make the costume more realistic. The front of the costume has a hinged doorway that lets a kid enter and sit at the controls, while the rest of the costume goes to the grownup.
