Now and then I use an empty slide with small grasshopper at the bottom to visualise an underwhelming market response to a major announcement. The lonely chirping of a grasshopper is often used in the The Simpsons and other movies to represent an (awkward) silence.
Here is an example of a slide design that might be too simple to buy on my store (you can if you want), you can easily recreate it yourself, subscribers can simply snap it up at no cost. Cover image by Elegance Thika on Unsplash
