Tiny symbol

The Action Group on Erosion Technology and Concentration announces a competition to design a “nano hazard” symbol. It points out that:
“Biotechnology, nuclear power, toxic chemicals, electromagnetic radiation - each of these technological hazards has a universally recognised warning symbol associated with it. So why not nanotechnology - the world’s most powerful (and potentially dangerous) technology?”

Feedback has designed one of these already, as it happens - but sadly you can’t see it because it is a thousand times smaller than this full stop.
