Mystique is a screensaver program I wrote to simulate the old Dancing Lines screensaver in IdleWild in 1990. The screensaver was later included as the default screensaver of Windows 95 using the name "Mystify," and continued to be included with Windows until it was replaced in Windows Vista where the name remained the same, but the program was quite different. Like Dancing Lines, the program displays several lines bouncing around the screen leaving trails behind them. I've added various forms of customization as well. Once you run the program, press the '?' key to see how to adjust the settings.
This is the last decent version before the developer started bundling in so much adware and eliminating free features that it became garbage.
