Its description says:
"Mighty Mouse allows you to customize your cursors with style - and it does so on the fly, without modifying any system files! Moreover, it allows you to customize all kinds of cursors available in the system - Arrow, I-Beam, Alias, Copy, Move and the Wait cursor. You can animate any cursor and import pre-made ones available at our website. Edit the cursors with the simplicity of copy-paste and drag-and-drop, then hit Apply, and you got it!"

So go get it, and good luck. :)

Thank ya, Another Scott. It's good to be here. :)
