Father Builds a Ferocious Tyrannosaurus Rex Halloween Costume for His Son

Redditor LordBrandon created a great, ferocious looking Tyrannosaurus rex Halloween costume for his son using foam, paint, and Teenage Mutant Ninja Turtles pajamas.

I made a model in 3D, then used software to split it apart into a pattern, then I hung the foam on the wall and projected the pattern with a little pico projector, traced it with a sharpie, and cut it out with an electric turkey carving knife. It really seemed to come alive when I painted the eyes.
