So Earth day is coming up and Robert Krulwich over at Krulwich Wonders have this mini-series of video on the good old Carbon atom.  Trust me, these isn’t any there about the pros vs cons of Global Warming.  Just some short entertaining and educational videos about the Carbon atom.  Highly recommended, go check it out.  I think it will eventually about four(4) videos, as of today, there are there (3).
