Every day the concentration of desk-bound warriors around the world is broken by the spontaneous serenade of the mobile ringtone. Open office space renders our privacy vulnerable. But, it is the occasional belting out of a one-hit-wonder, the Sponge Bob Squarepants theme song, or better yet pre-recorded personal message from friend, child, or lover that reveals our most intimate selves.

When you can't bring yourself to turn your mobile to off, consider going "silent" and investing in Pure Modern's SIGNAL Cell Phone Adviser. The Adviser is a simple frosted desktop mobile phone holder that detects your mobile's radio waves and begins blinking instead of ringing. If nothing else the modest $21 investment might be enough to stave off the stares, giggles, and rolling eyes of your coworkers.

Price: $21 at Pure Modern.

Note: Not compatible with Treos.
