You need about 24 ice cream sandwiches. Lay out one layer of them in a 9x13 pan. Next add your choice of caramel or chocolate fudge sauce. Then you can add anything from toasted almonds to cut up candy bars on top of the sauce. Add another layer of sandwiches and then cover the whole thing with whipped cream. You can get fancy and pipe stars or flowerettes along the edges.
Put in your freezer for a few hours of even the day before. Let thaw a tiny bit before serving for easy cutting.
