Vitalis — a hospital system, running for a hospital we invented.

Meridian Medical Centre does not exist and none of its patients are real. Everything else works: sign in as one of five people and the whole system changes around you.

As the medical director — wait times, takings, unclaimed HMO money, and who opened which record.
As a doctor — call the next patient, examine, prescribe against a live allergy check, order labs, discharge.
As the triage nurse — take observations and watch the queue reorder itself around who is sickest.
As the front desk — register, book, check in, take payment, chase the claim.
As a patient — your appointments, your results, your prescription, what you actually owe.

The one to try first: sign in as the doctor and prescribe amoxicillin to the patient in Room 2. She has a penicillin allergy on her record, and the system will stop you — then let you override it with a reason that lands in the access log under your own name.

Give it your email at the door and each action sends the message a real deployment would — the registration card, the appointment confirmation with a calendar invite, the discharge summary, the prescription, the result — within a few seconds. Or enter without one and skip the mail.
