+          Gravit is a gravity simulator which runs under Linux, Windows and
+      Mac OS X. It uses Newtonian physics using the Barnes-Hut N-body
+      algorithm. Although the main goal of Gravit is to be as accurate
+      as possible, it also creates beautiful looking gravity patterns.
+      It records the history of each particle so it can animate and
+      display a path of its travels. At any stage you can rotate your
+      view in 3D and zoom in and out.
