Infinity Mirror Clock Achieves Deep Portal Effect
Andy Huot has created an impressive infinity mirror digital clock that enhances the illusion with high-quality components and a unique design.

The clock utilizes RGB LED animations and a clever "stacked diffuser" vertical design for its 7-segment display elements, significantly amplifying the infinity mirror effect. The resulting appearance is portal-like, with smooth LED animations contributing to the illusion. Its 24-inch diameter adds to its substantial presence.
The core design involves lit elements between a reflective back and a partially reflective top cover. Huot's approach meticulously avoids imperfections, such as fingerprints, that could disrupt the illusion. The top cover features a 90% reflective film on acrylic, with professional application recommended for optimal results.
The build incorporates custom 3D-printed jigs for soldering RGB LED strips and uses putty to secure wires during assembly. The mirrored acrylic back wall has holes for mounting LED strips and routing wires.
A video documents the entire assembly process, showcasing the complexity of the build. While the design files for the 3D-printed parts are not freely available, the detailed documentation offers enough information for others to replicate the concept.
