Mike Giepert noticed something unusual on his Mac.  When he glanced at his Mac Dock, he noticed that the icons were spelling out the word browse.  You can see it in the above screen capture.  Of course, that realization caused him to start exploring to see what other word combinations he could spell out using only program icons.  Check out his discoveries here, along with the discoveries of some of his readers.

The dock is one of the features of OS X I like the most; the fact that you can now communicate via the dock is that much more impressive.  I just wonder how many possible words you could wring out of simple program icons?
