In the Qt status panel the six characteristics and the older
status conditions all have icons (similar to map tiles) drawn
above their values. (The 3.6 era conditions that I added all
have blank icons and are in need of artwork. 3.7 conditions
aren't implemented.)
Int, Stun, and Conf all feature a brain oriented towards the
player's right shoulder. The intelligence one is just a bare
brain, the stunned one features a black cloud over it, and the
confusion one has something over it that is cloud-like but
shaped differently from Stun as well has being white rather
than black; I'm not sure what that depicts. This transposes
the Confusion icon so that it faces the player's left shoulder
instead of right. Not a very emphatic suggestion of confusion
but seems a useful difference without requiring any artistic
competence.
