where do u look to find out how much insanity u have?

Currently only works with the default client. You will also hear voices once you start going mad.

ok, thanks

Those heads only show madness levels though, there's no visible insanity meter as far as I know. Definitively would be nice to see that progress as well, particularly for adding more precise values to the wiki's, so hopefully that'll be added in the custom clients eventually (*nudges Ender and Kandarim*).
