From the web: tracking with moving light
I've been searching for awhile if someone had done tracking searchlights project somewhere and finally found one:
Very well done, pity that the videos were not online at the moment. Idea is obvious and simple, but it makes the invisible surveillance visible, thus creating real experience of being tracked. I prefer this approach over the bigbrother reminders.
Interesting is also the notion how someone finds it intimidating and someone enjoys it, either as been exposed/observed or just because of the playfulness of it. This relates to a discussion few years ago with Heidi Tikka about the nature of light & darkness as protecting vs. exposing, which triggered my interest for light.
