Cryptatrope
An illusion created by physics
Drop in a glow stick or a small LED, give it a spin, and glints of light coalesce into secret messages and stereoscopic 3D animations. No electronics required.

Cryptatrope Adventure
"A groundbreaking concept and prop that we haven't seen used anywhere else in the puzzle realm."ESCAPETHEROOMers
A three-chapter adventure of optics, time, and causality. Print, decode, advance: each solved puzzle unlocks the next chapter, and by the end you'll have built three naked-eye illusions, finishing with a stereoscopic mechanical hologram.
The core illusion (free)
Cryptatrope FX
"Chosen as MakerWorld's Featured Model, a showcase for top-tier excellence."MakerWorld
The core effect with no story or puzzles attached, just the pure "wow." The FX pushes the visuals to their limit. Several eye-popping designs available.

About
The studio
Prime Tower Designs is led by Mike Brunswick, who spent 20 years in technical program management at Microsoft. When his 3D designs found a following on MakerWorld, he turned to design full time, founding The Brunswick Workshop LLC with his wife Elizabeth.
The studio focuses on optical mechanisms and kinetic objects: engineering principles turned into things you can hold. Mike's work has been honored in multiple 3D printing design contests, including a first-place finish in Bambu Lab's global Magic Trick contest, and he hosted MakerWorld's "Old World Magic" contest, which drew over 600 entries.
