Thinking about moving the piece forward without spending ages up a step ladder, I decided this week to make a little model box cube (another cube hooray!) that is to scale and mirrors the 8ft white cube space. 

Here's some images of the ideas I've been working on:

hanging shapes

with a projector light on it

from the back

covered sides and floor

with light shining on it

cling film and cellophane walls
