Hmm.... art or what someone appreciates as art or beauty is in the eye of the beholder and yet it is a core aspect of being human with deep evolutionary origins ( see Denis Dutton's Ted talk -
http://www.ted.com/talks/denis_dutton_a_darwinian_theory_of_beauty?language=en). Some of us math averse people fail to grasp the beauty in mathematical equations and I'll include Einstein's here too - though I'll risk being hung, drawn, and quartered.
Steve Jobs took a class in calligraphy at Reed College before dropping out and then heading to India but always considered himself to be an artist - though he technically wasn't one. Unlike Jim Henson, he couldn't do sketches of his designs or cobble together mediums to create his Apple creations - like Henson could with his Muppets. Jobs, however, could communicate his ideas and thoughts (often quite bluntly) on industrial design to his teams at Apple on what the iPod, iPhone, or iPad should look like and how they should work. But it was a largely a trial and error process and the focus was always on the end product, not the money.
madeinuk - if you read Walter Isaacson's biography, you'll see how Steve Jobs really relished industrial design and would keep looking at Braun and Cuisinart appliances as guides.
Also John Lennon, Clapton, Keith Richards, members of Pink Floyd and Zeppelin, many other UK rock and rollers from the 60s went to art school before they became famous musicians and it's not a coincidence either. (
