What you're building

You're building the tool that makes people leave meetings early: enter attendee count, average salary, and duration, and watch a live-ticking dollar counter show exactly how much that meeting is costing the company, second by second. It's simple arithmetic, but visualized as a live countdown-style ticker, it becomes a surprisingly persuasive management tool.
