Stonehouse - Communication through light

As a group we have decided that we are going to follow the communication through light theme that I mentioned in a previous post after creating the long exposure pictures on Union Street.  I developed this idea as the exposure pictures we took created very loopy lines of light due to the movement of the car that looked like writing.  This made me think of the concept of communication through light which can be dealt with in a number of different ways in terms of this project.  Firstly it links with the projection as the projection itself will be made of light and is also a way of communicating information.  There are also a number of ways this concept has been dealt with previously such as with Morse code which uses light to communicate through sequences such as those below:

I then thought of how light could be used in our projection to communicate something further.  It then occurred to me that perhaps we could do some kind of projection that when captured in long exposure would communicate something to the viewer, but without the long exposure would continue to keep its message hidden, alike to that of other long exposure images shown previously.  The following is an after effects mock up of something like this showing the two states of the projection, with and without long exposure:

This mock up was influenced by Sam's attempt at showing how a projection may work for our ideas (http://thebillatron.wordpress.com/2009/12/03/stonehouse-floor-ideas/) and demonstrates that this method would work quite well, even without the long exposure as the activity on the floor made by the projection is dynamic and engaging and would likely have an effect on the people who use this part of the pavement.
However there are bound to be other ways to look at communication through light and so I will continue to investigate this in my next posts.
