Laser: the screen's distance, pitch, yaw and roll are sliders (the beam ray
is intersected with the turned screen; the drawing shrinks only when a
steep screen would push the figure out of view), and the afterimage can be
turned off. The membrane is now a slack 50 Hz balloon whose split rocking
pairs land in the bass, so it draws loops ~60% of the time instead of ~25%.
Radial: fading trails can be turned off; the number of frequency bands and
volume steps are sliders; ghosts fade from the dot's own color into the
background; a 4096-point FFT and interpolation end the flat bass arcs; and
"Even out bass and treble" takes the song's overall tilt out so the dots
sit on a circle.
Preferences → Appearance → Visualizer picks Bars (as before), Radial dots
(the EQ in a circle: angle is frequency, radius is volume, moving dots
leave light-gray ghosts that fade over a set time), or Laser (a mirror on
a speaker membrane bouncing a beam onto a screen: simulated membrane
modes, D·tan(2θ) reflection, dwell-weighted brightness). Double-clicking
the panel opens it big; a click closes it.
