Why filter out the crypto assets?

Because including them makes the ranking meaningless. Tokens priced in tiny fractions of a cent would occupy every position, and the question the chart asks — what is a dollar worth around the world — would go unanswered.

Can I trade at these rates?

No. They are indicative reference rates. Any actual conversion carries a spread and fees, and the rate you are quoted will differ.

Yes. It comes from Coinbase's public exchange-rates endpoint, key-free. Nothing is invented or simulated, and if the source cannot be reached the saver reports that instead of drawing something plausible.

Does it cost anything or need an account?

No. Every screensaver here is free, runs in the browser and needs no sign-up. This one uses a public API that requires no key.

Six Hundred Ways Screensaver

The Six Hundred Ways screensaver shows what one US dollar buys in national currencies, drawn from the six hundred-odd rates Coinbase publishes against the dollar. It runs in the browser with nothing to install; press ESC to exit.

How the Six Hundred Ways screensaver works

The saver reads Coinbase's public exchange-rates endpoint, key-free.

No account and no key: the request goes straight from your browser, or from this site's own refreshed copy of the feed where the source does not permit browser access.

Values are drawn on a canvas that resizes with the window, so it works on a laptop or a wall display.

If the source is unreachable the saver says so on screen rather than showing stale numbers as though they were current.

A worked example

Sixteen currencies ranked by units per dollar, bars scaled logarithmically because the range spans several orders of magnitude. The full feed mixes national currencies with hundreds of crypto assets; this filters to national currencies, because a combined ranking would really just be a list of which token is cheapest.
