In python using tkinter, I want to create a program. The program
can have various classes and methods but I want it to have circles,
triangles, and squares. Each shape movies in a certain way, like
circles can move linearly, triangles can be affected by gravity,
and squares can only go up and down. If the shapes get too close to
one another then they disappear and a new shape appears somewhere
else. I want this program to run continuously.
