Summary

A new liquid crystal laser that can dial-up any wavelength of light you need, a laser-powered projector technology that turns any surface into a touch-screen, and a laser that fires salvoes of X-rays to make light work of unlocking the molecular fabric of matter are the focus of this week's laser-led show. We also meet HECToR, one of the world's fastest computers that just got a tenfold power boost, and David Braben unveils the credit-card sized Raspberry Pi, the world's smallest home micro he's helped to invent...
