This Doctor Who replica psychic container may not be useful for communication, but it would make for a pretty sweet night light.
From the product page:
This replica of the psychic container features motion-sensitive light changing effects. Tap the top to turn on the white glow. Tap again for white flickering mode (the most psychic-looking of the effects, in our opinion!), and tap yet again to go into color mode which cycles through a rainbow of colors. The Mark of the Corsair graces the front, reminding us that a Time Lord is eternal. The Doctor Who Time Lord Psychic Container makes a fun desk accessory or a nifty night light for your bedside table.
