LogCast is a simple tool to make Android Logcat logs more readable. Requires Shoes (http://shoesrb.com/) to run.

The icons are from the Tango Desktop project: http://tango.freedesktop.org/
Run logcastviewer.rb with Shoes, then choose the logcat file.
Sometimes it crashes for no reason. I don't have a clue why that happens :P
