I have restored a 1937 K6 red telephone box and installed it in my garden with access from passers by. I use it to experiment and perform with computer voices and melodrama featuring a version of my own voice created by the wonderful Cereproc. The first performance was Christmas Eve 2015, nobody attended. Until then I am testing two webcam streams showing a view of the outside and the inside of the box. As you may observe not much is happening, but if you are very fortunate a spider will spin its web over the lens or a cat will mark its territory.
If you wish to read more about this and the ‘incident’ during its creation please go to http://www.gravityisahat.com and search for ‘K6’ or ‘telephone box’ or ‘ward’ as in hospital.
