Smell-O-Mints for Mac

From John Schilling:

Smell-O-Mints is a Periodic table of the elements for the Macintosh. It's not as full-featured as a lot of other Periodic tables out there, but it's free and looks very nice. Especially if you put it next to the coffee table by the ferns. Click on an element symbol to get a little more information on the item, like atomic weight, radioactive properties, and atomic number. You can use the popup menu to switch between the basic table and a table of solids, liquids and gasses, and more.
