Drug Classification Screensaver
The Drug Classification screensaver shows the WHO's Anatomical Therapeutic Chemical system from the NIH's key-less RxNav service, from the broad body system down to the specific chemical group — the whole taxonomy of what drugs are for. It's free, runs in your browser, and ESC exits.
