Different folder icons depending on contents

Bruce Tognazzini:

> I should be able to tell, by looking at the outside (...) how much material is within, how old the folder is, and how long it has been since I’ve opened it. I’m not talking about surrounding it with text; I’m talking about using that 24-bit color space to add visual attributes. For example, the more the folder contains, the thicker it should appear. The older it is, the deeper the color should become, with age cracks appearing after several years. The time since I’ve opened it could be represented by cobwebs or dustiness.
