Grape
or
Variations on a Quartic Polynomial with Complex Coefficients
Grape can be seen and heard only on PowerPC Macs and prefers newer Macs and iMacs.
Press "esc" or "Q" or "W" to quit. Grape won't quit instantly.
Please view Grape at each of your monitor's color depths: millions, thousands, 256, and grays.
At less than millions (especially 256 colors), please view Grape with and without dithering.
Press "D" to turn dithering on and off.
Set your monitor's resolution to 640 x 480 to view the graphics full-screen.
At higher resolutions, press "C" to display sliders that let you control the graphics and sound.
Press "C" again to hide the sliders and cursor.
If your Mac displays a Control Strip, you can change your monitor's color depth and resolution
while Grape is running.
Grape hides the Control Strip, but it will reappear when you click where you last saw it.
