When I was a kid, I always loved when some real-world annoyance, like my dog whining to go out before she just gives up and pees on the floor, distracted me from my game long enough to trigger an idle animation. Sure, they don't really contribute to gameplay, but these little moments help sell the 8-bit characters' personalities. Just think of Sonic and his classic foot-tapping.

So, if you're looking for something to do, you could do worse than a montage of classic idle animations. Enjoy!
