This is the thing nightmares are made of.

Adam Savage’s Tested team visited this year’s Monsterpalooza, a convention for special effects and makeup artists where they get to showcase their passion projects. Out of all the creations I saw on their walkthrough video, my favorite was the hyper-realistic Ren and Stimpy masks from bad-ass sculptor Andrew Freeman. You may have seen some of Adam’s work on Hansel and Gretel Witch Hunters and The Devil’s Carnival, but nothing quite like this.

Watch Adam’s interview with Norman Chan above and then head on over to ImmortalMasks.com to see more of this sculpting genius’ work.
