Compound Card Screensaver
The Compound Card screensaver shows a rotating card of real chemistry from PubChem at the NIH, key-less: molecular formula with proper subscripts, weight, IUPAC name and hydrogen-bonding counts. It's free, runs in your browser, and ESC exits.
How the Compound Card screensaver works
The saver reads PubChem at the NIH directly in your browser — no key and no account.

It refreshes on a schedule, so what you see stays current.
