Comment from Artist

I created a warning symbol that is unique but at the same time that had some
resemblance with other universally recognized technological hazards
symbols, so people identify it immediately with something dangerous.
The central element is a cube or a 2 dimensional hexagon with one
square in each corner, representing the molecular structure of
nanotubes. However is my opinion that the meaning of it is not so
relevant, but what is more important is that the symbol is eye-catching, as hazard symbols have a familiar look so it is easier for people to remember and associate with the nanohazard issue.
