Analogue Loaders makes waiting for your computer to finish what it's doing way look more entertaining than it actually is:

It's a pity there's no mechanism (as far as I know) by which I can get my Mac to adopt some of those images to use instead of the standard, boringly monochrome and resolutely 2D progress animations that come with the system. A couple of those look far more fun than the standard progress indicators. 1

Besides, most of the delay I see tends to be due to waiting for data to download rather than waiting for the CPU to have time to process it.
