Core77.com reports on a sophisticated coffee cup which requires a key to operate. Wow, wish I had one of these here!
"Office life and its attendant foibles (light-fingered co-workers et al.) are starting to spawn some interesting designs. Designer Efrat Gommeh's anti-theft coffee cup, spotted on GearFuse, requires a key to be used; failure to use the plug-like key provides your coffee with an unintended exit strategy.
Military versions to be used on submarines will apparently require two officers to use two keys simultaneously."
