This top advertisement could be good as a palm tree idea. showing people when its awful weather here you could be under a palm tree instead. this would have the # tagline of T.D too. Good idea, novel, talking piece.
IBM created a color sensitive interactive billboard that changes color depending on what your wearing. The billboard has installed a color detection camera that changes the color of the LED lights inside to match what it sees in front. The billboard was designed by ad agency Ogilvy Digital for IBM’s Smarter Planet campaign. via PSFK: http://www.psfk.com/2011/09/ibm-interactive-billboard-that-changes-color-according-to-what-youre-wearing-video.html#ixzz1hI4vJDjI
