If you want to get a wall clock, you can choose anything between big digital ones to little classic analogue models. But if you want one that's really clever, the Flat Life Clock might be the way to go.
With the form factor of a picture, the Flat Life Clock is just the image of a run-of-the-mill alarm clock, except that it actually works. All you have to do is plug your newly hung picture into the wall — which is admittedly a kind of weird to have to do — and it'll start blinking away, like a weird portal to an alternate dimension where there is nothing but an alarm clock floating in the vast emptiness.
It might not be the most efficient time-telling solution because it's rather small, but it's sure to make friends and family go "aha" at its cleverness — and yours by extension for owning it. And if that's not enough for you, there's a Flat Life Light as well. Both go for $US150, which might be a little steep for a visual joke, no matter how clever. But come up with a Flat Life Bookcase to go with it and I'm sold on the lot. [Areaware via bookofjoe]
