Ferrofluid

Watchface

Description

A fluid simulation in the palm of your hand! Or, on the back of your wrist...  
This watchface uses a modified double density relaxation sim and "magnets" to form fluid particles into the current time. Configurable color, "font," sim duration (per digit change), and backlight-triggered simulation.

Warning! Although it's highly optimized, this will push your Pebble to its limits - with the default settings expect about *half* of normal battery life (~15 days on Pebble 2 Duo). 

Thank you to Clavet, Beaudoin, and Poulin at the Université de Montréal, upon whose paper the sim is based.
