My students had to present a PowerPoint presentation and I was tired of seeing bad PowerPoints. So I made a PowerPoint of all the major annoying things that you could do using PowerPoint.
It contains moving bits, bad backgrounds, bad fonts/colours, annoying sounds, and everything in-between. The goal is to show students what a bad PowerPoint slide looks like so they can do the opposite. Ironically this bad PowerPoint is actually a visual aid for my lesson on good PowerPoints! Yay!
As I go through the slide, I explain what would make it a better slide. Kids get a kick out of it because I try to make the examples pretty bad.
