I was inspired to build this project after visiting a museum in Scotland that had a room full of infinity mirrors that made it look like you were floating in space surrounded by stars. I thought it was the coolest thing ever!

My infinity mirror design is definitely a DIY project. Everything you need is easily obtainable at the hardware store and plastics store. The trick is making your own big one-way mirror out of acrylic sheet and privacy window film.

This project is easy to build — no expertise in electronics is needed. You’ll use inexpensive electronically controlled Christmas lights, which are available year-round on sites like Amazon. Customize your mirror by choosing lights in your favorite colors or ones that blink or change hues.

In Step 8, if the film side of the acrylic is mounted with the film facing inside, should not then it be applied to the NON counter-sunk side back in step 6?

  I found that step confusing as well. I have privacy film in my kitchen and the film is on the inside. It’s so you can see out but people can’t see in. The film should not be on the side facing the mirror, it should be on the side of the observer. I don’t get it.

  the two mirrors should face each other so it reflects off one another, creating an infinite loop of the lights reflection

In order to reduce the cost of the build it might be much cheaper to use a stretched and smoothed reflective mylar surface for the bottom mirror with just the backing rather than an acrylic mirror.

How much roughly does it cost to make this?
