Best foot forward, 50* a second

Our tiny, innocuous little geckos can walk upside down on glass at 50 steps a second, or the same speed as the hum we (Australians) get out of mains applicances like flourescent lights or solenoids.

Apparently, US & Chinese scientists have been watching the little suckers run about. The little lizards switch on & off the stickiness by rolling their toes, first to expose as much van der Waals (inter-atomic stickiness) forces as possible, then to separate their spatulae one at a time for the next step.
