When you walk into Heather and Jon's house, you can't miss the Periodic Table that takes up most of one wall. It was an extraordinary gift to Heather years ago from an extraordinary friend.
Science museums around the world should hope to have such extraordinary friends of their own so that they can acquire the new interactive Periodic Table displays produced through a partnership of Theodore Gray and the Red Green and Blue Company. If you can't wait until the exhibit is available at your local science museum, check it out online. If you can be deal with the relatively long download times, you can click on the individual elements and get a glimpse of how wonderful the physical display must be. I was most fascinated by how many of what I thought were unusual elements turn up in common use, something I first learned from The Radioactive Boy Scout.
When I first started reading the description and noticed that they had actual samples in the display, I wondered how they contained the radioactive ones. Then I clicked on a few - they just have a radioactive symbol and they say "if we had an actual sample here, you would be dead." (:
