EvoSpaces is a Swiss-wide research project sponsored by the Hasler foundation. It involves three partners: University of Zurich, University of Lugano and the University of Applied Sciences in Geneva. The overall goal of the project is to explore novel ways to visualize and navigate evolving software systems in a 3D environment. In this paper we briefly describe the particularities of the project and the results obtained so far. 1 Project Summary The EvoSpaces project (lasting from Jan 2006 to Dec 2009) aims to exploit multi-dimensional navigation spaces to visualize evolving software systems to ease their analysis and maintenance. Specifically we address the following questions:
