The real meat here is the progress unit. It declares the IProgress interface and two components that implement IProgress: TThreadSafeProgressBar and TThreadSafeProgressLabel.

The central idea is that you can drop these components on a form, fire off a background thread, and the thread can display its progress using these components via the IProgress interface.

As a demonstration, I include some code I wrote to compute the digits of PI using the spigot algorithm.
