This is a short video of high school video game design teacher John Gainelli displaying the 'glitch' in one of his student's games to the rest of the class. Apparently it's not actually a glitch though, the student just turned off his character's gravity to see what would happen. Whatever, I'm more surprised that there are video game design classes in high school. We definitely didn't have those when I was a teenager. The closest we ever came to video game design was playing Snake and Drugwars on our graphing calculators in math class.
Keep going for the video.
Thanks to David M, who just wishes there'd been a pastry baking class in high school. Right?
