Geoff Smith sent this link to SenseSurface. It seems like a neat idea, but I wonder about it. For one thing, I wish they’d show the pickups, because it’s unclear how finicky they are. Do they have to be placed directly behind the knob, or not? How well do they stay on? Are the knobs attached magnetically or with suction or something else? I have to admit that even though I abuse my laptop screen, I’m not willing to put these on the screen without some more info.
