new circulated book piece

I’ve just made a new circulated book piece called six surfaces, all of the same dimensions but otherwise different and am about to send it on its way. It involves making a recording of an object dragged across six different surfaces which are supplied in a folder. Each recipient replaces one of the surfaces with a new one before passing it to someone else. Each recording is therefore slightly different, depending on the new combination of surfaces and the object used to activate them. I’ve made the first recording which can be heard here, and will add subsequent recordings once I receive them.
