Lenticular images (1960s)

摘要

A footballer kicking a ball;a face morphing between two expressions.These and thousands of other 'moving' pic- tures have been brought to life by lenticular plastic - which causes an image to shift when it is tilted.Lenticular images - first produced in the US in the early 1960s - are based on a simple idea although their manufacture has,until recently,been quite complicated.
