Protozoan Triptych #4

Under the microscope we can observe single-cell organisms - protozoa - growing and merging in a nutrient solution.

The microscope has an array of many different visualization modes available for use by curious investigators (24 in all!).

Press "1","2", or "3" to switch between the 3 main visualization modes.
Press "q" to switch between "quantized color" and "full color" modes.
Press "i" to switch between normal and inverse (or backlit) visualizations.

Press "r" to switch between portrait and landscape visualizations.

Press "4" to obtain a triptych of all 3 visualization modes at once.

Press "s" to save the current visualization as a png file.

Note: the previews take a few minutes to materialize. So be patient, and watch your protozoa grow and flourish!
