Origami and technology go together pretty well. Lightweight, efficient structures... and animal shapes. But there's not more "origami" than the humble paper crane. Now, courtesy of a small, light, power-efficient microcomputer from Rohm (a Japanese company: don't let the name fool you), the crane can fly. Better still, it's remote-controlled and can even keep itself afloat for around five minutes, according to the spokesperson. It's almost the most Japanese thing here at this year's CEATEC. Almost.
