+VisualOS is a "visual simulator of an operating system", that will help
+study and understand the way a real systems work.
+
+It allows the user to insert processes in the running system, assigning them
+properties (memory usage, processing bursts, IO accesses) and VisualOS will
+dynamically show different graphical representations of each subsystem. It is
+also posible to select the algorithm to be used in each case.
