I made a life-size, battery powered, faux campfire. It can go anywhere to give a space a false sense of warmth or keep the monsters away, whatever your preference.
I modeled the shapes in Blender, sliced them up in 123D Make, laser cut them from chipboard, paper-mached over the forms, then plaster coated and painted them. The faux fire is courtesy of some battery powered twinkling LEDs that I picked up on post-holiday clearance. Overall, a fairly ridiculous fun project.
