Lava lamp is our kind of phone charm

We've never quite understood the appeal of mobile phone straps and charms, but maybe that's just another sign of our advanced age. But now we've finally come across a trinket that we can relate to: a mini-lava lamp.

And this isn't just any lava-lamp charm, according to Popgadget, but one that lights up when you get a call. The "Astro Light" from British designer Mathmos is also available as a bulb, but it's the lava lamp that holds a special place in our heart. The only other icon that would be more appropriate from our misspent youth would be a bong.
