USB flash drives are used for productivity, general storage, and even espionage — and in a seemingly ridiculous twist, they can now also be used as vibrators thanks to the Duet Lux. The New York Times looks at this new device: a memory drive that doubles as a vibrator using a silicone tip. The invention was originally intended purely for use as a vibrator that could be recharged via USB, but the compact design led focus group testers to ask if it could also be used for storage. As unusual as it sounds, the booming vibrator market is nothing to scoff at; the NYT says several companies have been working on making the vibrator a "lifestyle product" through design and innovation.
