Despite appearances, this position is one of the more tricky in the Scout Walker Kama Sutra. One Scout Walker lies back with their head propped on the ground and their legs tucked up to their chest. The other Scout Walker mounts them, splaying their own legs back behind them, and proceeds to rock and thrust - being careful as they go as their partner is particularly prone and vulnerable beneath them, taking not only their full weight but the full weight behind their thrusts and motions. This position is known as "wrecking" as, on the battlefield, two Scout Walkers surprised in the act by the enemy whilst in this position can freeze, power down and quite possibly be mistaken for scrap metal: it resembles nothing more than one scout walker crushed under another who has been shot out of the sky in mid-leap. There are stories and "urban myths" floating around claiming that some have escaped with their lives by doing just that, but these are generally taken to be apocryphal. This position is popular not only for the energy you can put into it, but also because it allows the two of you to kiss, though your not pressed into each others faces either - so you can shy away from halitosis with tact.

New Scientist reports about a thing called 'e-skin', a thin flexible plastic film with embedded electronic sensors. This e-skin can measure temperature and pressure changes. Covering robots with this film will give them a human-like sense of touch.

Impressed? At the University of Tokyo they are already thinking of a future e-skin which will also sense light, humidity, strain and ultrasonic sound. Very touching indeed!
