United Visual Artists have a lovely new piece called Hereafter, which is very similar to elements of my Time Sketches in that it layers frames from a video stream with minimal opacity so that it builds up over time.
They’ve done it much better than I did, though, not only because of the wonderful setting and the custom housing by Based Upon but because they use a high-speed camera to massively slow down your ‘ghost’ image. I can see it changes the style of the interaction and gets people moving around in space in interesting ways.
There is a basic element of interaction which is about seeing the results of your actions. This seems to always be the most fruitful with cameras - we’re all narcissistically fascinated by our own images of course. But there’s another aspect that I think Hereafter and Time Sketches (and plenty of others) plug into and that’s the idea of warping time. Slow motion and time-lapse cinematography are both fascinating and I think it’s because they’re on the fringes or outside of our normal senses of perception. X-Ray and infrared are also interesting in this respect, but there’s something about messing with time that seems to engage people, especially when it’s their own image.
(p.s. I did another Podcast with Matt Clark from UVA for Core77 that will be online soon. I’ll post a link when it’s up.)
