Someone the other day was telling me about new DLP-based spotlights which can detect the silhouette of the person being targeted and light up just those parts of the beam, so there isn't a bright circle cast around them. And of course, once you have that, you can beam patterns just onto specific people as they walk around. Pretty fun idea.
