The use of barbed wire is significant not only because it is an interesting use of metal, but more importantly it represents the pain and inevitability of death for those, including nine of my relatives that died in Nazi concentration camps.
There is a lot of hope being offered with the use of glass especially when used in conjunction with the barbed wire in this way. I feel that it was important to allow the glass to behave naturally when faced with an obstruction in this case barbed wire. This to me mirrors the collective social consciousness of the then society, hard razor sharp obstructions social unrest, dangerous rhetoric being fought against loudly and silently by good people.
The glass is forced through the gaps in the barbed wire-escaping areas of violent high pressure in favour of low pressure but is willing to fail and crack enroute to achieving state of balance and equilibrium. This i find is often mirrored in society. The glass behaves like society in times of institutionalized oppression and force being imposed on the people. It has two options: either expand and break through collectively or fail to do so as a unit and break.
