Pretty abstract for me, eh?
There’s an app called ‘Camera for iPad’ which allows your iPhone to be used as a remote camera for an iPad, which doesn’t have a camera of its own. Quite fun. It shows a ‘viewfinder’ on the iPad, so of course I pointed the camera at that.
So this is a view, taken on an iPhone, of a view on an iPad of what an iPhone is seeing when the iPhone camera is pointed at the iPad. The kitchen ceiling light is reflected in the iPad screen.
Q, years ago I experimented with video feedback, with which you can obtain extremely rich moving patterns. The simple trick was to turn the video camera (iPhone, in this case) upside-down, and make sure the screen was filled with the image (rather than any borders showing). This is makes a mathematically very sophisticated environment, akin to an Iterated Function System – remember those? – chaos and fractals leap out of the screen. Well, at least they did with old analogue camera/TV combination. It also helped to skew the colour response a little (ah – weren’t analogue controls just the best??!). You can seed a pattern by waving your hand in front of the camera, or using a light, etc. It’d be interesting to know whether you can achieve the same effects easily with a modern digital set-up! I should try and digitise some of the old VHS tapes a friend and I made…
