A "toon" is a representation of a model object, drawn in context. For example, galaxy catalogs typically contain a number of parameters such as RA, Dec, color, magnitude, size, and so on, and astronomers make lots of scatter plots in two of these model parameter dimensions at a time. Plotting each galaxy as a "galtoon" allows more dimensions of the model parameter space to be explored.
You can input galaxy catalog data pertaining to halos, disks and bulges, and the galtoons will plot themselves as a superposition of "blobs" that represent the component properties. Blobs can have position, size, ellipse axis ratio, orientation, colour and brightness, with values chosen by you.
Code and data for the above plots can be found via these links:
