Have you bored with the traditional outlook style notification: play a ring sound, pop up a dialog, then show you the coming appointment/task? It's an ordinary reminder, no fun, no extra action. If there are some animated cartoons to playing, things will change.
Think of that, when your appointment coming, a vivid agent pops up, reads the notification content to you, and plays some animation to show the message. A lovely agent popping up makes the coming reminder more acceptable, more interesting. What's more, listening to the appointment, not reading the appointment free your eyes from the text.
Moreover, eReminder provides an easy way to add your personal favorite characters.
