Bells & whistles vs. visual communication
Been reading a lot of stuff lately about cognitive overload. Wondering what your thoughts are on stuff like animations and snazzier-looking slide designs (and even special audio stuff like lots of sound effects).
In the past, most of my work has been fairly low on the bells-and-whistles meter, but I've been thinking that there's some value in making things look and behave in a more visually interesting way. But on the other side of the aisle, it seems like a lot of designers are kind of poo-pooing courses that have too much glitz. How do I know when it's too much? Are there best practices for such things?
