From the BBC today comes news of a new type of projector developed in Germany. The big thing about this projector is that it’s not big at all. It’s under 16mm wide and 9mm deep.

While that’s news in itself, the most interesting thing about this article is the closing comment :

Other laser-based video projectors have been created, but have been limited to the size of a matchbox.

It’s an indication of the pace of change when people refer to a highly advanced and extremely complicated piece of technology as ‘limited’ to the size of a matchbox.
