More development work

Today I did more development work, making shapes with polystyrene, whilst also making a rudimentary, realistic sketch of the 'transformer' figure, taking into account how I'll bind the pieces, such as tape, pins etc.
I used a kitchen knife to cut out a shape for the E4 symbol, making a small one as a test. Then I used a bigger piece of polystyrene to get a larger logo.
It's easy to cut, but it can crumble and break if you're to rough with it.
I also thought about how it'll have to be evenly lit, and if I want to make anything 'jump', I will need 'invisible thread' to suspend the object, I also need to think about how I'll suspend it.
