Algorithm Method

A number of individual tracking points follow the mouse at slightly different rates.
During each frame those points move towards the mouse and plot their positions.
The varying tracking rates create tendrils of color that can resemble Moire patterns, or the "Qix"-style line-bounce of "Mystify" screen savers.

Color is accumulated in an additive manner using a higher resolution pixel buffer.
The additional precision of this intermediate buffer allows for the gradual accumulation of very smooth gradients.

The additional precision is also used to plot antialiased sub-pixels, further smoothing the display.
(this is effectively equivalent to 2x oversampling, then downsampling with a simple box filter)
