Using foamcore for wall and projection of shapes

Messing around with two pieces of foamcore that have been taped together to form a hinged wall, then a cutout for light to shine through against the back “wall”. The “bars” are projected on the back and when the bars are flipped up (hinged with duct tape) you shoot through the hole. I think you could probably make the hole taller and shoot through that to get a bigger window effect.
