Virtual Space OOO has announced 3D Molecules Editor for Mac OS X. The educational app lets you build and manipulate 3D molecular models of organic and inorganic compounds.

The key features of 3D Molecules Editor are 3D printing support and the "Test yourself" mode that allows learners to check their knowledge of the 3D structure of molecules. Important information about the molecule can be displayed. For example, it's possible to visualize the atomic orbitals, see electronic effects using arrows and identify bond lengths and element symbols.

3D Molecules Editor 1.0 costs US$2.99 (though it also offers in-app purchases). It's available worldwide exclusively through the Mac App Store in the Education category and requires Mac OS X 10.7 or higher.
