I love having ship's bells in the background to mark the hours and keep me on track. Now we can hear these sounds right from the browser window!
Click the SPEAKER icon to enable sound (most browsers require it), and click KIOSK to make the app fill your screen (which I do on the old little Kindle Fire on my desk). You can also set QUIET HOURS. Finally, click the CLOCK icon to make the page tick every second (like a real live clock!). Local cookies should remember your settings.
Feel free to drop me a note at rgreencf [at] gmail.com with bug reports and ideas for future enhancements!
