It's like driving your car. Backward is *almost* like forward, but changing
direction all the time is an entirely different experience.

The best algorithm I've come across (CLS-222) uses a combination of
vibrato (doppler effect), reverse vibrato (doppler effect of waves reflected
in cabinet), pan modulation and tremolo for treble and a combination of
vibrato reverse vibrato, frequency dependent pan modulation and tremolo
for bass.
