I do not know the developer who was responsible for the dock icon animation for program updates in OSX.  Mac users are aware of what I speak.  When Adobe Acrobat has an update, for example, the icon for the program will magically elbow its way into your Dock’s real estate, usually at the end between your open programs and your downloads.  Once it’s established itself, it begins its proud, happy, never-ending job of bouncing (boing, boing, boing) at the bottom of your desktop until you either 1) force-quit the program, or 2) acquiesce to its demands.  I usually opt for the former, as I prefer to update on my own timetable.  Which is why I have been clicking on “remind me tomorrow” when I get the Yosemite updates notification popup in the upper right quadrant of my screen for several weeks now.  I suspect Yosemite will take matters into its own hands very soon as I cannot be trusted.

At any rate, the reason I bring this up is that I am oftentimes amazed at its persistence.  It will, literally, bounce for days. Nonstop.  Someone programmed them that way.  Some mad, sadistic developer knew that we could not just let icons bounce incessantly at the bottom of the screen and have the wherewithal to pay it no mind, as could easily be done with a small red notification icon.  Sneaky.
