Power Point

The worst of Power Point offenses occurs when the lecturer is ready to move onto the next slide but has to play through an extra thirty seconds of animation.  I also hate annoying animation sounds.  It's frustrating when there is either too much or too little information on a slide.  I don't know why people use light type as it's difficult to read, and I also hate it when pictures move around too much.  The best powerpoint I ever saw focused on Renaissance Art, with each slide devoted to one or two works.  It was an effective way to present such a large amount of material.
