German uber-brand Siemens has been at the vanguard of home appliance design for some time. So, behold its brand new DiscControl technology, which takes the idea of the iPod's touch wheel to the knobs of a kitchen stove. And then allows the touchy-wheely knobs to be removed should one's kids be going through that awkward "what-do-burned-eyelashes-smell-like" phase.
It's all down to one simple thing: magnets. (I say simple, but there are some things that are, well, not.) My only gripe, however, is that this technology is only compatible with Siemens' induction and glass ceramic hobs.
