Atträctor by Friedrich Söllner is an easy to use tool to transform grids according to given attractor geometry. This tool was developed for a beginners Grasshopper workshop at the Städelschule architecture class in Frankfurt/Germany (this is where the ä comes from).
By using the Graph Mapper, a built-in Grasshopper component, the user can avoid most of the proximity calculations. The Graph Mapper can now be used to explore the mechanism of attractor point transformation. This makes it a simple and intuitive tool to get quick results, especially for Grasshopper beginners.
