As you walk through the door of Distortions Monster World at the Denver Pavilions, you’re greeted by an oversized zombie head. You can walk inside it, have a photo taken, and then move on through the brightly lit, 19,000-square-foot interactive installation showcasing the various ghoulish creations of Distortions Unlimited, a Greeley company that has been making handcrafted Halloween props, monsters and animatronics since 1978.
