         | Yes, but you can also play around with it. x,y maps to u,v
         | where t is a constant that may be animated and you can use many
         | functions. Nice to build intuition. Here is an example:

       | and the result is drawn on the right square. The result is
       | generated by either a Ph function (mapping the complex value
       | coordinates to new coordinates) or an f function (mapping the
       | complex value to another complex value), but not both. You can
       | animate either function by using t as a parameter. t has the
       | specified constant value when not animating. You can't iterate,
       | so this won't make fractals.

       | This is very cool. I do think you could boost engagement a lot by
       | offering a dropdown menu of transforms that you know work well
       | and result in cool visual transformations. It would also be cool
       | to have a palette of recognizable shapes (like letters, numbers,
       | emoji) that you could quickly enter in and see how they get
       | transformed instead of just freehand drawing and lines.
