This Meetup was canceled.
An example of an improv game:
One player becomes an imaginary machine part, making their body into the shape of that part, complete with a machine like motion and appropriate sound effect. One at a time, subsequent players add themselves as parts, thereby expanding the machine and it's function.
I will come with a bunch of improv ideas like this, but I'd love for others to input ideas as well. We can make the meetup's direction match our collective mood at the time.
