The latest Android phones continue to cram more camera tricks up their unibody sleeves, but what about your current smartphone that's barely a year old? That might be where the Eye-Plug comes in. Hidden inside a humble stand deep within Computex here in Taipei, the USB-C accessory plugs into your (currently Android-only) smartphone, adding another camera sensor to your phone for front- and rear-facing dual camera frivolity. (That's where you need that handy reversible connection.) I tested out a prototype, with full production set to begin later this year. 3D selfie videos could be a horrifying reality.
