LED evangelist Teddy Lo combines art and commerce in real world

A suggested war cry for those save-the-worlders who have seen the light (and are partial to cold war-era sloganeering): better LED than dead. The proclamation's modern application refers to the light-emitting diode's capacity to slash electricity consumption and bring about our exodus from the greenhouse of doom. No longer simply red readouts on rudimentary calculators, LEDs are the power behind pictures on jumbo TV screens, the transmission of information from remote controls, the intensely annoying scrolling text up the sides of the ICC in West Kowloon, and much more. But first, a taste of the gospel of the holy diode: Planet LED, recently published by Teddy Lo.
