Bought Birthday for a 7-year-old boy. The twelve-year-old wanted to play with the same and for the adults a fun. On four transparent plastic Platen painted. Through individual lighting of the plates creates a flow similar to "flipbook". By the sequence of four painted images created movement. The images can also be lit individually. The plastic plates are but certainly over time scratch the images you look in the dark and it is not well very disturbing. The drawings can be easily wiped off with a damp cloth. All in all, a successful gift.
