From Think.Art Computing:
Sticky Notes is a handy program for any version of Windows that lets you stick notes to your screen and send them to others. Use them for reminders, for messages, for telephone notes, to-do lists, Web and e-mail addresses, office memos, or anything else that occurs to you. The built-in Voice Recorder lets you record and store voice message for each note that you can play back at any time. You can change the color and size of your notes at will, set them to ring an alarm at a given time, lock them to protect their contents, and temporarily move them off the screen by hiding them. Version 2.1.3 may include unspecified updates, enhancements, or bug fixes.
