Read full descriptionHide full description
Federgraph is a function plotter app to visualize a special built in function z = f(x, y) in 3D. The physical model behind the app is a system of springs. The built in function produces a variety of colorful pictures, some of which appear to have a face. Changing the parameters of the physical model will trigger a recalculation of the image.
