In web applications in the 1990s, it was pretty common to see animation (animated gifs, marquees, etc.) -- since then, the industry has pretty much established this as a no-no for (professional) websites.
My question is whether such a standard exists on the handheld platform. Admittedly, I'm a bit of a gadget luddite, so I don't have much experience with iPhones/iPods/Android-phones/Blackberries/etc. to know if such a thing exists or not.
