An outfit called Pega Design has come up with this beautiful desk lamp. Called Pumplight, the light's brightness is controlled via a small bladder — rather like the thing the nurse inflates when she's taking your blood pressure.
But that's not the only thing the control bladder does. The more you pump it, the bigger the balloon that acts as the shade gets. The dimmer the light, the smaller the balloon. With offices in Taipei and Shanghai, Pega is an offshoot of Asus and, judging by its website, has all kinds of innovative ideas up its sleeves — including a rather beautiful transparent laptop concept that you can see on the designboom website below.
