In icon view, every file, folder, and disk is represented by a small picture—an icon. This humble image, a visual representation of electronic bits and bytes, is the cornerstone of the entire Macintosh religion. (Maybe that’s why it’s called an icon.)
OS X draws those little icons using sophisticated graphics software. As a result, you can scale them to almost any size without losing quality or clarity. If you choose View→Status Bar so that the bottom-edge strip shown in Figure 2-4 appears, you get a size slider that you can drag to the right or left to make that window’s icons larger or smaller. (For added fun, make little cartoon sounds with your mouth.)
Figure 2-4. Once you make the status bar appear, you can choose an icon size to suit your personality. For picture folders, it can often be very handy to pick a jumbo size, essentially creating a slide-sorter “light table” effect. Icons can be an almost ridiculously large 512 pixels square.
The Mac expands the notion of “an icon is a representation of its contents” to an impressive extreme. As you can see in Figure 2-5, each icon actually looks like a miniature of the first page of the real document.
Because you can make icons so enormous, you can actually watch movies, or read PDF and text documents, right on their icons.
