Open Source Software Makes the Invisible Man

"A University of Liverpool mathematician claims 30-year-old open source software has cracked the equation that will allow scientists to make objects--such as humans, tanks or even entire islands--invisible.

"The mathematical theory builds on earlier research into cloaking technology by Imperial College's Professor John Pendry. He developed artificial materials (or meta-materials) that can make light sweep around an object, theoretically rendering it invisible. 'You play geometrical tricks,' Pendry told PC Pro. 'You force [light] particles to go around an object just like water goes around a stone...'"
