Some Brazilian enthusiasts have hacked an ancient lift/elevator system with one goal in mind - the ability to send an email to call the lift to their level.

Furthermore the system can detect when the lift is at the required level and email the notification. Then the passenger can mozy on over to the car and start their ride. More in the following video:
