There's something quite simply wonderful about watching someone work up a serious sweat while you sit rooted to your backside. Maybe it's the sheer slothful pleasure of knowing it's not you. Or perhaps it's deeper than that; the desire for all of us to possess the body beautiful, despite lacking the will to make it happen. Hmmm. Whatever one's motivation for enjoying the sight of hard work in others, there are few greater pleasures than the sight of Push-Up Preston of Muscle Beach getting down to business. Preston is a muscle-bound body builder rendered in skin-coloured plastic. He'll work-out for your hilarious delectation. Then work out some more. Simply wind him up and watch this doyen of firm muscle tone go hammer and tongs at his mechanical press-ups. Up and down. Down and up.

Reminiscent of the real-life Adonises in places like Venice Beach, it's the way his goes about his duties so uncomplainingly and with such robotic attention to detail that marks him out as special. It beats exercise any day in our book, and makes a splendid addition to the armoury of distractions on your desktop. Really rather good.
