For the last animation which is an action of your choice I decided to go with a good ol' desk flip. I didn't sketch any of this out and instead had the idea in my head which I generated into a quick animatic.
The main things I want to include is some angry concentrated typing, followed by an indication that something went wrong, then the character losing it and flipping their desk over.
I explored other ideas such as what sets the character off: either a blue screen of death which is universally recognisable or perhaps a crashing sound. The characters sudden change of mood should be easily associated with something going wrong with the computer (everybody's been there).
