Cryptatrope
An illusion created by physics
No electronics required. Pop in a glow stick or LEDs, and spin. Glints of light form mysterious 3D animations.
3 ways to experience
1A standalone optical effect
Cryptatrope FX
"Chosen as MakerWorld's Featured Model, a showcase for top-tier excellence."MakerWorld
A device with no story or puzzles attached, just the pure visual "wow." The FX pushes the optics to their limit. Several eye-popping designs available.
2A print-at-home escape room
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.

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.
