Tehnology world has seen a lot of Digital Picture Frames. However, on the #PLS2015 there are also music boxes that can show images. And picture frames which are also loudspeakers. Or speakers that show images. Optical acoustic elements or music making photos. Nevertheless... the mixing of optics and sound in Hall 9.1. is certainly good to marvel at. Whether the singer of your favorite band is shown to coincide with the listening or if you want to enjoy nature with relaxing music - there is something for every ear and eye.
