Icons for Plug-ins, Hardware, and Removable Media

Plug-in icons look like stackable components, with the associated application identifier on the left side and a plug-in–specific image on the right.

Hardware icons represent devices as you most often see them: on your desk. Because these devices are also frequently handled and carried, people are familiar with them as three-dimensional objects with weight. Therefore, the hardware icons reinforce their association with real objects.

To help users distinguish between external devices, their icons provide a region for an identifying symbol (FireWire, USB, and so on).

Removable media such as CDs, floppy disks, and PC cards are depicted the way they look when you hold them in front of you—that is, the perspective is straight-on.
