Another object of the Amsterdam Light Festival, called "Triangolini" made by Israelian artist "Hogar Elazari". It is a flat light wall covered with a pattern of a number of layers semitransparent triangular stickers. The public can pull a sticker off and move it to another place and so change the pattern.
For me it was a nice shadow play to watch the people and making photos.
