At the Museum of Science in Boston, we are developing two storytelling shows
that might have that impromptu structure you are looking for. We have yet to get
these on the halls, so this is all theoretical at this point.

We are going to have an actor on our live animal stage and in our Theatre of
Electricity for 45 minute segments, telling stories connected to the subjects-
animals and the natural world, and electricity respectively - and while they may
go into a character to tell a particular story, they are not in character the
whole time. There is no beginning-middle-end to the stories. We want visitors to
be able to stay for one or many stories, with more of a free flow than our
scripted shows. They will have signs near them declaring them Museum
storytellers and some other info, and we want them to be able to interact freely
with visitors as themselves. The stories themselves range from myths to
biographical stories to personification of physics
