Write a program that displays 500 colored triangles on
the screen. You must choose the color of each triangle randomly
by selecting random values for the amount of red, green, and blue.
Then select three random points for the vertices of the triangle.
Each vertex will require two random numbers: one random x-value
and one random y-value. This means that each triangle requires
nine random numbers.

Finally, put all this stuff inside a loop that repeats 500
times.
