traced portraits

Although I avoid buying things with obnoxious plastic packaging, it seems to find it's way into my home anyway.  I'd like to make it all go away forever, but while it's here, I'm trying to make peace with its existence. 
With plastic from a 'product pack' that came as a 'gift' for spending silly amounts of money on groceries, here is my small attempt of making something from nothing.

The rigid plastic box made a nice little clear panel on which, with our heads inside the box, our faces could be traced upon with a permanent marker.  The idea originally came from a science museum where one participant sat behind a Plexiglas divider while the other used erasable markers to trace their face.  It's an activity in observation, perspective and hand/eye coordination, as well as entertaining. 

The kids like to put the box on their heads and turn one of their parents' faces forward and pretend to be that person.  Also entertaining, and, sometimes, boarding on the insulting if one of us is in a bad mood.

What to do with this plastic monstrosity that I somehow made into a keepsake?  For now it sits on the shelf, available for play.   There is some potential of turning it into a lampshade by covering the inside with tissue paper for an extremely low wattage bulb.  I could also cut the box into panels and make into a collage for the wall or window.

What do you suggest?
