Smartphones are inarguably an addictive class of devices, and not just because they put an endless font of information at your fingertips.

The very experience of holding the phone and touching it is itself associated with that pleasure — so much so that you might wish you were doing it even when you don’t want to actually use the phone. That’s when you need one of Klemens Schillinger’s “Substitute Phones.”

The devices, if you can really call them that, are inert pieces of heavy, high-quality plastic in which are embedded stone beads that let you run your fingers along them to simulate various gestures.

The beads roll in place, giving a similar frictionless feel but (I presume) also a pleasant little finger massage.

“The object, which some of us describe as a prosthesis, is reduced to nothing but the motions,” explains Schillinger’s description of the… object. “This calming limitation offers help for smartphone addicts to cope with withdrawal symptoms. The object as a therapeutic approach.”
