It's an impression device. You can use it for all the applications any other imp device is used for. Get one ahead for a Q&A, drawing dupe, thought of card, PK time without the spectator having to name their thought of time out loud, and all that is just the tip of the iceberg. If you want more ideas go read Anneman and Corinda for starters and then you can start delving into all the other literature out there for other applications for an Imp pad.
