HERE WE ARE again, in the holidays...
This time every year I like to suggest a uniquely Modernist approach to Holiday Lighting. If you have obscure glass on the front of your house, try putting your lights BEHIND the glass.
Not only does this hide the wires, making the lights appear to float, but the glass produces a pretty astounding optical effect. Just look at these pics...
..this doesn't even begin to capture the effect when in motion, as when driving by the house at night. These YouTube videos come closer...
You can play with the distance between the lights and the glass to get different effects. Farther away, the auras are bigger and more dim, closer, they're brighter and smaller.
If you like, post a reply, with pictures of your results!
