Light Wave

At this risk of sounding a bit smug, this tablet-like device is most likely not what you think it is. The Sigma80 is, in the language of the wall-hung toilet world, an actuator plate; in other words, it's a flushing mechanism. But unlike the typical push-button models, this offers completely touch-free operation. Waving a hand across either the short or the long light stripe triggers a half- or a full-flush, respectively. A winner of this year's iF Product Design Award, it was developed by Tribecraft.
