This is a interactive slide show. in this project, the sprites each use the broadcast block to send a message to the stage. The green flag block is used just to set up the first stage background image - this has text to explain what the condyle is. The stage has scripts with the "when I receive" block. These are programmed to change the background image, then play a recording, wait a little bit then play a sound effect when the stage switches to a copy of the background that has a red dot on the condyle.
