Lawrence Berkeley Labs has a movie here that shows Carbon atoms in live action movement in a sheet of graphene. That is the stuff you make when you drag your pencil across a sheet of paper and it may be one of the more important materials of the 21st Century.

Absolutely fascinating, but aren’t you mistaking graphene for graphite.
No, graphene sheets come off the graphite tip of your pencil as you slide it across the paper.
I hate the future! They keep changing it! When will the paperless office arrive? Where are our aircars? Where’s my home nuclear kit? Give us back our old future!
Sorry, nuke, the future isn’t what it used to be, is it? But then, I suppose neither is the past.
Seriously, that is a fascinating film clip. Thanks for posting it, Dale.
