1-hour submarine ride for insomnia, demonstrating a sleep aid app for mobile and web that I'm working on, called "20,000 Zs". The goal is to get you sleepy through soothing sounds and images, while letting you estimate the time remaining just by listening or glancing at the scenery. The app allows any duration from 1 minute to 60 hours. The boredom you are feeling is a feature, not a bug.
