The infinity mirror has lights that seem to go very deep into the frame. It's particularly dramatic in a darkened room. However, when the mirror lights are off and the room lights are on, it's just like an ordinary mirror. The basic idea is that there is a one way mirror at the front of the unit. Behind is another mirror. The lights reflect against the mirrors which in turn reflect against each other which give you the effect of depth.

Our model what made with leftovers: scrap lumber, a string of Christmas lights, two panes of glass, and some leftover reflective film designed to control sun and reflect it back out of your house.   When the highly reflective film is applied to glass, the glass become a one way mirror.

Here are the components and their sequence, starting at the back:

1. Cardboard backing piece painted black
2. Glass to which sun control film has been applied. This film comes in several densities. Get the most reflective density available (80% or greater). The black backing makes this into the equivalent of a regular mirror.
3. Outer frame made from 1"x4" boards. This frame should be big enough to leave 1" space all around the inner frame "D". This space houses the electrical cord. This outer frame can be stained or painted to suite your decor.
4. Inner frame made from 1/2" or thinner slats with holes drilled every inch on all 4 sides. Drill holes to accommodates sockets in strings of lights and let the number of lights control the size of this frame. Start your basic construction of this unit.
5. Christmas tree lights: use a string of 100 or 1 pair of 50-light strings. We used assorted colors because that's what was available, but you'll attain a more dramatic effect will all white lights
6. Blocks of wood glued at all corners to hold inner and outer frames in position.
7. Posterboard mat cut to hide gap between inter and outer frames.
8. Outer glass also has sun control film applied to it.
9. Frame of molding holds glass in place and give finished look to front.

All of the components within the frame that are visible should be black. Be sure to leave a hole in the back for the wire and plug.

There is the basic idea, but you can adapt it to your own design. Use more lights or make the frame oblong instead of square. You can use the basic idea as a wall hanging or lay it flat and make an infinity table. In fact, go into a mod furniture store and look at some of the store bought models for ideas. Also, look at the price tag (from $200), and go home to reflect on how you'll save doing it yourself.
