This is a free Mona Lisa screensaver, with no advertising or limitations, in which you travel forever, step by step, down an endless mysterious tunnel of Monas. You may find, eventually, that you are being gently sucked into your computer screen, so be sure to wear your seat belt.

The screensaver needs no installation. Just download the file "infinite_mona.scr" by clicking on the preview animation above, and put it in your Windows folder. It will then appear in your Display / Screensavers list.
It's a 553k standalone executable file, which doesn't create or need any other files, and doesn't touch your registry. It can also be run just by double-clicking it. To completely remove it from your system, just delete the .scr file.

There are no user settings for this screensaver, and no help file, except this. It runs at a fixed frame rate - not quite as fast as the animation - and for smoothness it always runs at 800 x 600. This will not affect your computer's resolution.
