One possibility is to encapsulate your code as a Dynamic item
(simplest example is in a Manipulate, but using more general Dynamic
functionality allows much more creativity) with an appropriate

This has been covered in this group at times in the past (I don't have
time to give an example right now ---yes Fermat Lives!).

But such an approach can cause your example to automatically update at
a specified interval.
