Algodoo

This reads data from a disk via a laser.
To open the disk tray, press and hold right arrow.
To close it, left arrow.
To make a new data disk that makes the screen display text, make any object with a custom variable named "data", then put any text into it, then insert it into the disk tray(make sure it touches the laser!).
Yes, this is Algodoo-Only.(AO):P
