+\abstract{We describe a method for implementing drag-and-drop of irregularly
+shaped rigid 2D objects while maintaining the invariant that no two of them
+overlap.  Our method allows users to naturally and easily manipulate adjacent
+objects.  We also describe our handling of stretched rope-like objects.}

+\section{Dragging Rope-like Objects}
+In addition to solid objects, Pen has support for rope-like objects, including
+string, rubber bands, and wires.  Like rigid objects, we want to maintain the
+invariant that these objects don't overlap, but there are a few important
+differences.  First, ropes can change shape during dragging, as they grow longer
+or shorter, or wrap around other objects.  Second, while the result of dragging
+a rigid object depends only on the point where it is dropped, dragging rope-like
+objects depends very much on the path along which they are dragged.
+
+We have decided to support only ``stretched'' ropes --- ropes that
