In case you haven't already heard or seen the photographic periodic table of elements, it is really worth the time.  NOTE: Nick Mann, the chief photographer for the table was homeschooled.  Also excellent: the periodic table of videos  with the wonderful Professor Poliakoff.  I also read  Graphene Will Change the Way We Live up on Dr. Kaku's Universe blog over at Big Think.

another beautiful periodic table is below and that's my son studying yesterday at right
