Just finished this little project. This is my abstraction of Caño Cristales, a river in Columbia. This was made using layers of acetate sheets with geometric graphics printed on them sandwiched between varying thicknesses of acrylic panels. Unfortunately, the acetate and acrylic are not very optically clear, so the desired effect of seeing the depth of all the layers to the bottom is not as strong. However, as seen in the last two photos, if viewed in front of a bright enough light, the depth and layers are more clear.
