Here is my version of a monster in a box. It uses a PIR to activate it and a prop 1 and AP-8 for the control and audio. It uses 2 pneumatic cylinders and a scuba tank to power it.

Looks great!

Cool!

Cool!  I made one several years ago, I need to get some video of it and post it.  Mine also uses a PROP-1 and an AP-8, plus an RC-4 to control some other portions (light, smoke).
