Of the hundreds of millions of designs of iPads and other popular mobile devices at this year's CES, the one that seemed most out of place was "Sky and Water I," drawn by Dutch artist M.C. Esher in 1938.
There it was, on the same table at the Lux Mobile booth as designs featuring Marilyn Monroe and a host of other movie stars and modern popular icons.
Then there was the Esher-designed iPad covered with 18,000 Swarovski crystals that had been dipped in 24 karat gold -- a limited edition case that sold for a cool $3,000.
As you can see, it's beautiful. I've got no problem with that. It's just that pairing Esher with the likes of Humphrey Bogart, Elvis and Hello Kitty seems, well, discongruous.
