### Geometric Cake

In this tutorial, we will model the Dinara Kasko algorithmic cake in Grasshopper. First, we will start with a series of square cells and then by moving them up, scaling and rotating them, we will form the base curves. Then we will use the grasshopper attractor techniques to connect the scale factor to the attractor and finish the tutorial.
