Mount your Pebble on your wall for fun and profit.
My shower had two screwholes in the wall, about an inch vertically apart. (24mm to the civilised c...haps.) Leftovers from a previously borked soap dish from a bygone era.
The Pebble smartwatch makes a pretty fantastic waterproof remote for my shower tunes, but doesn't like constant exposure to hot water. And who wants to wash with a watch on, anyway?
So. The mission was clear. Mount the pebble on the wall.
Now. Off to the shower with Bon Jovi and ZZ Top, as god intended.
