In this project I used rectilinear forms. Usually rectangular shapes are dominant. There are also several triangular shapes. One side of the model; starts with a rectangular shape rising upward by getting smaller on the other side the big triangular shape is shrinking turning down a triangular form. This two main space has a few links from the edge to middle. In the model there is no symmetry and shape distributions are irregular. I put my model name water slide because models left side with triangle is like stairs and the left side when we looked at the bottom pulling into the inward which is the slide part.
