Kekule
Kekule is a molecular visualization app for the 64-bit Windows
Kekule is a fork of Roger Sayle's old 16-bit Windows 3.1 RasMol 2.6 app, last updated and released in 1995.
Kekule is meant to aid high school and college chemistry students in their organic and inorganic chemistry studies by allowing you to visualize molecules in 3 dimensions on your laptops. This will greatly increase a chemistry student's understanding of molecules and their structures.
