The Sun Sending Word Screensaver

The The Sun Sending Word screensaver shows space weather notifications from NASA's DONKI, key-less. Every row is an alert issued to spacecraft operators and power grids — CME is a coronal mass ejection leaving the Sun, GST a geomagnetic storm arriving at Earth. The lag between a CME notice and the GST that follows is the two or three days the plasma takes to cross ninety-three million miles. It's free, runs in your browser, and ESC exits.
