Why we chose this
 
The Albert Clock is named after Albert Einstein and inspired by an apocryphal anecdote: that Einstein was bad at math.
 
Designer Alex Schindlbeck, who conceived this clock for a small Paris-based company, set out to turn classroom boredom into mental calculation skills.
 
He gave the standard alphanumeric segment font a makeover, with improved readability of numbers and mathematical symbols.
