I guess this website is going to have to change soon: http://isgo1point1outyet.com/
1outyet.com and make a subdomain, so it could be
isgo1.1outyet.com ?
It was a demo in a talk by @enneff at Railsberry 2013: https://github.com/nf/go11
The site should update automatically once the repository is tagged.
I kinda figured they wouldn't leave the polling time at 5 seconds.
