8. Haunted Portrait Gallery with Changing Lenticular Art
Create a wall of ancestors that holds a chilling secret. Source cheap, ornate plastic frames from thrift stores or dollar stores and paint them with a coat of metallic bronze, highlighting the details with black wax to make them look heavy and antique. Print out vintage, sepia-toned portraits of Victorian families. Using a steady hand and a hobby knife, replace the eyes of the portraits with tiny, pin-sized holes. Mount red micro-LED lights behind the eyes so they glow faintly in a dark room. Alternatively, use lenticular sheets that transition from a normal portrait to a decaying zombie or skeleton when viewed from different angles, giving your guests a sudden, delightful fright as they walk down your hallway.
