The purpose of this project is to create a computer tutorial program that shows and explains structure of atoms and describes how bonds between atoms occur, as well as provides capabilities to access information about chemical elements such as atomic weight, number of electrons etc. via an interactive periodic table. BTutor is intended for use mainly by students to help visualize and better understand basic processes that occur on atomic level. It may also be used by teachers to support their lessons with visual presentations. The program is copyrighted with GNU General Public Licence, it is an open-source freeware.

Right now, you can also download the Interactive Periodic Table, which only has the periodic table with data in it. (Go to Downloads -> click on the link and choose the Interactive Periodic Table package)
