Edit: This will become public to anyone to use this summer. Probably around time of RDC England if I go
Like a month or so ago, I started an interactive Periodic table. Then that lead to more updates… which lead to a plugin version I can show anyone in offline mode. 
Standard View (I clicked Cesium):
Zooming to the Atom:
Zooming to the Info:
Zooming to the Table (Normal View):
Zooming to the Table (Radioisotope View):
The more red the element is on the table, the higher the percent of the isotopes are radioactive
If you want the full version, you will need to contact me. (If you want one for free, discuss it with me via PM or Skype.)
For a trial version, it can be found here: http://www.roblox.com/Periodic-Table-Plugin-Trial-Edition-item?id=205881661
