A Screenblanker with high security which does not burn in the graphic into the
screen when CPU is really busy. It's funny to watch, runs only@ under Amiga OS
Release 2.04 or newer. Rotor was inspired by a flightsimulator. The routine
which was used to simulate the spinning rotor of a plane is use in this blanker.
The effects are somewhat mesmerizing and spindizzy. Include c source, authors:
