Objective
Image the world without real mirrors, what could a magic mirror look like. San Francisco does not snow over the year, as a girl comes from northern part of the country, I really miss the white Christmas. This prototype is specifically made for Christmas in SF, associate with christmas tree with led light coded in Arduino program, and using camera to reflect the player, and player can catch the snow flakes on the screen to enjoy the White Christmas.
