For those of you who have no idea what the hell is going on, the extension he's talking about, called "The Grouch," had only one function: Everytime you chose "Empty Trash" from the "Special" menu, an animated Oscar would pop the lid off of your real Trash icon, still with the trash lid on his head, sing a clip, "Oh, I... Love... Trash!..." and then pop back down. Genius, in a real cartoony way.
I have no idea how the extension figured out WHERE your trash icon was on the desktop. But it would, and then he'd pop out (making the icon appear bigger than it really was), and then pop down.
Could iCan animated everytime the trash is emptied, AND make an animation outside the icon's area?
Wow. I'm an old fart when it comes to Macs.
