Jumping message

I' building a listener-agent program that will pop up to the screen with a message each time an event is received.
I'm interested in making the pop-uping itself (the appearing process of the mesaage) to look nice and original.
How can I do that in WPF?

Thanks.

Look around the internet for WPF tutorials and samples to find something similar to what you like. With WPF, you have all sorts of control over colors, shading, transparency, etc.
