Installation steps
Mac: Install Manifestation Station.saver once. Select it in Screen Saver settings, then choose Options → Import intentions and select your downloaded HTML file.
Windows: Install the free Lively Wallpaper app. Put the downloaded HTML in a folder of its own. In Lively, choose Add Wallpaper → Choose a file and select the HTML. Follow Settings → Screensaver, completing Lively’s one-time screensaver setup if prompted. The Microsoft Store version must keep running in the background.
To update your words, download a new Screensaver file. Import it again on Mac, or add the new file and select it in Lively on Windows. You only install the player once.
