An augmented reality idea: Take a photo!
Edited
Make a cool photobooth or a neat AR project of your own design?
You can save a photo of yourself in your costume to share! Here’s code for a button actor that takes a screenshot of whatever is on Stage:
Notice how the actor hides itself as the screenshot is taken. The broadcast “cheese” might tell all the other on-stage buttons to hide, too! Save the file and name it whatever you like! Then you can post it anywhere you like.
