Marius Klug recently requested a feature that one might change the neutral point of dynamic space from (x=0, y=0) to some other location. This would allow to set an EmotionalAttendee to have a certain predisposition to experience positive or negative emotions. In fact, it is somewhat related to the initial idea behind an early implementation of "SETPREVAILING", which could be used to temporarily change an EAs prevailing mood in dynamic space (see page 87 of http://www.becker-asano.de/DA_Komplett.pdf).
