Tons of free icon sets

The icon for the folder of active design jobs on my computer is a hamster. I know it's completely juvenile, but it's been entertaining me for the last ten years. If you'd like to replace any of your standard folder or application icons with something sillier, here's a great roundup of 70 free icon sets. (Thanks, Celeste!) Be sure to check the licenses for each, but most are available for commercial use on websites, too.

Among the cutest: Desserts, terrariums and appliances.

To change your folder or application icons on a Mac, follow these directions or open the new graphic file in Preview, select all, and copy it. Do a "File > Get Info" on your destination icon, click the old icon at the top of the window to select it, then paste. On a PC, try these directions.
