Busy Simulator makes app notification sounds to make you seem busier than you are

Brian Moore's Busy Simulator enables you to play the notification sounds of Slack, iMessage, Outlook, Discord, and other apps so that you sound busy, to your co-workers or perhaps just to yourself. Turning them all on creates a very unnerving app symphony that captures the zeitgeist. Try it here!

From the instructions:

Use the sliders to increase the speed of the insanity or whatever.

Tip: turn "Original Sound" to On on Zoom for best effect.
