The group I'm associated with in Edinburgh is prosaically referred to as the MRG (Mathematical Reasoning Group) but when feeling more fanciful we get referred to as the DReaM group (Discovery and Reasoning in Mathematics).
The Dream talk is a weekly hour-and-a-half work in progress talk, in which the use of slides and projection equipment is frowned upon (but handouts are tolerated) and audience participation is encouraged. AB also has a gong which, at least when I was a regular member of the group, he used to sound just before the Dream talk thus removing the perennial excuse that you were involved in something and had therefore forgotten that the talk was taking place.
