This applet creates an animated display by continuously summing four sine waves into an array and drawing this array in the applet window. Use it to measure the graphics and "CPU" performance of your Java virtual machine. Send results (in frames per second) to wayne@codon.nih.gov. There is newer version of the benchmark (Plasma2) that uses a 640x480 window, draws the image to the screen at 1:1 and synchronizes image generation and image display.

* Using Windows 95, JDK 1.3 runs the applet at 67fps for about 30 seconds then starts
page falting and the frame rate drops to 25fps, with jerky animation.
