Hunter's comment
the peppergram is an inverted pyramid made from plastic. it doesnt require laser equipments for this to work and it is a DIY product.
The PepperGram projector works because by darkening the room and using a bright 3D video, the 4 sided pyramid made of semi-reflective, semi-transparent material produces several such images so you can view a realistic image at all 360 degrees around. Its super nifty and easy!
