This looks like a cool rebranding (or reimplementation?) of gltail: http://www.fudgie.org/.

We used to use that for monitoring some internal logfiles at Facebook a few years ago, and it was actually (embarrassingly?) useful beyond just eye candy on a few occasions, when something broke and suddenly the big screen was full of gigantic balls bouncing around and hitting each other.

It'd be nice if this could tie into varnishlog as well to show which hits are being cached. Seems like this visualization might actually be useful though. Sure it's pretty, but it's coherently presenting the data. If you're having a dos attack from one IP, it'll be immediately noticeable here. Cool project.

When running multi-threaded it would be visually interesting to see multiple paddles mapped to threads responding to requests.

Would be awesome to have a real-time visualization like this of traffic.

Has anyone used this? Experiences?

It's awesome if you're after something to visually show off your apache logs.

Eye candy!
