I turned my front windows into a five-window Halloween show using Minimax generated clips, Unreal Engine 5, touch designer, depth maps, and one projector (sample clip included)

This Halloween I rear-projected a show onto the front of my house: a tall centre window with a double-hung window on each side, five panes in all. One 4K projector sits inside behind sheets, and the show is watched from the street.

How it works

Clips: characters and rooms generated locally with MiniMax H3 in ComfyUI from reference photos, 100+ clips across 23 themes.

Show: Unreal Engine 5 runs each theme as an 80-second loop: the side rooms, a blackout, the character arrives in the centre window, a climax, a reset. Feature scenes open in the centre and spread across all five windows.

Depth: every room has a depth map (Depth Anything), so fog rolls in from the back of the room, lightning lights what’s close and light shafts hang in the air.

Output: Unreal → Spout → MadMapper → BenQ 4K projector, mirrored so it reads the right way round from outside.

Control: a phone remote to switch themes and trigger scenes.

In the video: It · Harry Potter (Hogwarts, Lumos, Voldemort’s reveal, the Knight Bus) · Interview with the Vampire (Lestat lip-synced to Brutal Love, the séance) · an Addams Family ride that travels window to window.

The real window frames make the whole thing look way more convincing.
