Can you elaborate on the 'hypnotic' lights? I've never seen or heard of this.

- fractallyte 11y agoI think it was UK Gatwick Airport, on the way to passport control. The passengers were shepherded into lines, and spaced at intervals above each line were ceiling-mounted cameras. Bright LEDs around the camera lens were flashing in rotational patterns - designed to instinctively draw attention, and hence make facial recognition easier.
- ethbro 11y agoWere there four lights? Or five?
- fractallyte 11y agoI really can't recall. I wasn't looking up!
