An infinity mirror is a pair of parallel mirrors that create a series of smaller and smaller reflections that appear to recede into an infinite distance. Infinity mirrors can incorporate light producing elements, e.g., LEDs, that are typically sandwiched between a full reflection mirror (in the rear) and a 50/50 mirror (in the front). This arrangement wouldn't work for me because the LED clock array (scavenged from an Anelace clock) I used was on a solid circuit board that would prevent internal reflection from taking place between the mirrors. To address this problem I had to eliminate the full mirror so I developed an "Infinity Chamber" constructed from two 50/50 mirrors (I applied the same mirrored film to each piece of glass). The LED clock was placed on the outside at the back of the chamber and in this way the light from the LEDs entered the Infinity Chamber and was allowed to "experience" the internal reflections typical of Infinity Mirror arrangements.  It is difficult to represent the extent of the internal reflections visible to eye using video or photos. In a well lite room I can typically see 5 copies of each light square while at night I can see as many as 7 images. The cherry case was constructed by John Parkinson, based on a prototype I had made, and the electronics were scavenged from an Anelace binary clock.
