This Is the Smallest Season's Greetings Card In the World

This Season's Greetings card is only 200-micro-meters wide by 290-micro-meters tall, the smallest in the world. Created by a team at the University of Glasgow, this nano-fabrication technology could be used in bio-technology sensing, optical filtering and light control components.

To give you an idea of its ridiculous size, u¡if you printed them over a standard holiday card, you could fit half a million of them. This one is printed in glass, however. According to Professor David Cumming and Dr Qin Chen, this technology could end in cameras, television and computer screens.
