Splines is basically an old X Windows program, xsplinefun, that drew colourful splines on your X workstation's display. Now you can have it on your Mac at home too. It works in any bit-depth, and tries to act sensibly on systems with multiple monitors. If it can find a display that's 8-bit deep it draws on that, to take advantage of palette animation. If you enable the ‘Adjust screen depth upon fade’ checkbox in DarkSide, Splines will switch the display to 8 bits if it can.
If you don't like the colour Balloon Icon in the fader, feel free to cut it out with ResEdit. If you do like it, paste it into your copy of DarkSide and it will appear in all your modules. But *don't* redistribute modified copies of DarkSide, or of this module.
That aside, feel free to distribute this module in any way you see fit - but remember it's freeware, not public domain. Send me some email if you like it. Thanks to Jim Calvin, this version now works correctly on multiple-monitor setups.
