Has anybody out there ever built the collapsing tree from Beckett's Act without words? I am trying to find an easy, low tech way of building a tree that is able to move onto the stage on wheels, and then lower and raise its branches. I am working in a completely open plan theatre with no flies or curtains although I will have some flats to hide a few things. Any suggestions how I could do this? All ideas welcome, I am running out of them. Cheers, Jon.
