NanoCAD is a
Java applet (formerly a
Scheme program) that was intended to eventually evolve into a useful computer-aided design system for
nanotechnology. While that goal has yet to come to fruition, NanoCAD has at least influenced the direction of more advanced projects such as
OpenChem[?] and
Fungimol.
The NanoCAD Java applet is available to tinker with at http://willware.net:8080/ncad.html
