Hollow Sights (www.hollowsights.org) is an option to look through an object, it’s a series of attempts to “objectify” our gaze through mobile phones, web pages that function as cameras, folding your device camera input into a 3D model and allow you to capture still photos video and control the camera source, hollowsights.org requires your permission to access the device camera but the app itself runs locally and no data is shared with the server at any stage.
