Spirex started out as a graphical ditty in DJGCC, an early port of Gnu C to MS-DOS (now called DJGPP). Spirex is based on the geometry of a Spirograph, only with continuously varying wheel sizes. In a fit of nostalgia I ported it to Java many years later. Due to popular demand I rewrote it in C++ and turned it into a Windows and Macintosh screen saver, adding many features along the way.
Features
- Swirling images based on a 3D extension of a Spirograph
- Texture mapping of 3D solids. Several textures are supplied, but you can also use your own images.
- Anti-aliased lines in 2D modes.
- Many parameters to explore so it never gets stale.
- Saving of user presets. Optional random switching among presets.
- Optional battery saver mode (Windows only).
- Multiple monitor systems get a screen saver on each one.
- Automatic checking for updates.
- It's free, (as in beer and as in speech.)
