We like cars, and we like art. Naturally, Chris Labrooy's Auto Aerobics series - computer-generated images of some seriously contorted 1968 Pontiac Bonnevilles floating in mid-air - instantly clicked with us. If the Pontiacs weren't floating or hollow, we could be fooled into believing the image is real. But where's the fun in that?
The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
