When we first saw this photo, we were thinking, "Whoa! Cool clock!" But then we read the caption underneath (a good habit to get into to avoid confusion on a plethora of subject matter), and realized this isn't a clock at all. It displays one number and one number only for the entire life of the product. This feature makes it useful for only one purpose: as a house number. But there's still one big problem...

Isn't the main function of house numbers to be hyper-readable from long distances? We can barely make out the number sitting right in front of it with no obstructions.

Still, it comes with one handy function we like in a super-tech house number: the lights turn off during the day thanks to an internal photocell.

The entire thing is "assembled" by punching out tabs to "spell" out your number. Pick a color and voila! Your very own punch-card house number. As a Floridian, I know this simple assembly is sure to confuse old ladies. Maybe they—and all of us, actually— should just stick to basic house numbers that don't get too tech-y.

This illuminated house number is from Tangible Interaction and was spotted at MoCoLoco.
