Hi, I made this to help my science teacher. When your students are getting up out of their seats and being naughty, this will scare them back into their seats! (J.K. it won't really.) Also works if you want to see who can stay still the longest.
I made this using the video sensing extension, and pretty much my whole class crowded me, so they were all testers. ;3 (P.S. Dexter is still the reason this exists.)
