Erlend Simonsen put out a program called gltail that creates a graphical representation of your log files.
I saw this a long time ago, but last night I finally started playing with it. It works quite well. I needed to make a small change to support an SSH gateway which you can get here: http://github.com/dshimy/gltail. On OS X, getting started was simple:
$ git clone git://github.com/dshimy/gltail.git $ sudo gem install ruby-opengl file-tail
If you want the dots to bump each other, you need to install the Chipmunk physics library:
$ cd vendor/Chipmunk-4.1.0/ruby $ ruby extconf.rb $ sudo make install
Beyond that, tweak the configuration file and enjoy.
