The two pictures above show two quick mock models of what IDEA 4 would have looked like.  Basically it was a fixed internal cylinder and a larger rotating external cyclinder.  A person would have stood in the internal cylinder as the external cylinder rotated.  The outer cylinder would have had pictures of significant buildings around Belfast at equal distances apart.  The experience inside the inner tube would have been interesting as the light coming in from the different coloured acetate sheets would have filled the space and this paired up with the pictures would have made out installation different, original and worth while. 

We had a slight problem on our hands as to how the external cylinder was to rotate. We thought we could make a simple circular track for the structure to sit on.  The downward force of the structure had to be spread out equally otherwise it simply would not work. We made two small models to try and think of ways of rotating our installation. As a group we engineered a way of doing just that. The idea was to get a line of coke cans on a steel track and set the structure on top... we did various weight tests to see if the cans collectively could withstand such a force and through calculation it was proven that they could. The cans had to be full though in order to do this. The two pictures below show our small models of our rotating system.

the picture above shows our first attempt at creating a rotating system however it did not work

Again we went against this idea because overall it was a simple idea made complicated. The rotating system was very technical and if it wasn’t made right could have ruined are whole installation so there was indeed a risk factor involved as well. The budget in creating this design would have been too much and if I’m honest the design and idea would not have fitted the bill.
