Many years back I watched that "Back to the Future II" show with my family on TV. Was amazed with what happened in 2015 as a young kid. Saw some of those: 1.) Self-lacing shoes. 2.) Holographic Shark Advertisement. 3.) Neon lights on the sidewalk. 4.) Smart glasses. 5.) Hoverboard. 6.) Self-drying jacket. But it's a month to 2015 and I'm yet to see all these!! The "smart glasses" might be an analog to the "Google glass", but less gawdy. The ones in the show has a mini LED-matrix showing stuff which might be an equivalent to today's OLED display. Those neon lights on the sidewalk might be today's lamp posts with LEDs. The "holographic shark advertisement"... not even in today. Hoverboard, self-lacing shoes and self-drying jacket are nowhere to be seen even as for now.
