Reversible Siding

Ever seen multiple ads at a sports arena? To sell more ads in the same space the billboards are made out of triangular segments that rotate to display three different images, each of which comes from a different company that paid them money. Anyway, it would be neat to make siding based off of a system like this. You could change the color of your house quickly and easily.

Now, before someone posts "Baked: See Housepainting", hear me out. There's a real good reason you might want to do this. A darkly colored house absorbs a lot of heat from the sun, and that can significantly cut the heating bill. You see lots of darkly painted houses in the higher latitudes. In reverse, lightly painted houses have lower cooling bills. You see lots of them in the South. This way, you can have both. You could even link the system to a thermostat and have it maintain a set temperature.

Of course, that won't stop you from changing the colors at a whim. Heck, if you really want to drive your neighbors nuts you could set each row to a random color or have the colors ripple and change constantly resulting in something truly odd looking but that's not the point. We're talking about saving money and reducing wasted energy here, no need to be a jackass really. Hehehe....
