Stickies

Stickies is a Macintosh application for putting Post-it note-like windows on the screen, with short reminders, notes and other clippings.

The first version of Stickies was written by Apple employee Jens Alfke and included in System 7.5. It is also included in Mac OS X, now with features such as transparent notes, styled text and the ability to embed pictures in notes.

Stickies contains an easter egg in System 7.5. Here's how to find it:
 * Create a new note.
 * Type Antler!.

In the Mac OS X 10.4, Stickies is one of the widgets included with Dashboard.
