I decided to work as a pair with Islay Sellar as we had similar ideas - Information can be found on her blog as well - http://foelcastell.wordpress.com/
We decided we wanted to use Symphony Hall as our location so we documented our walk to see if it would be possible.

Although the timing was a bit too long we felt we could make it work if we walked faster.
We chose Symphony Hall as we felt it inspired us both and gave us a lot of options to work with.
