+\section*{Android Application Screenshots}
+
+The following screenshots show the grazing boundary editor that
+is included with the Android application:
+
+\begin{figure}[h]
+\centering
+\begin{minipage}{.5\textwidth}
+  \centering
+  \includegraphics[width=.8\linewidth]{images/app_editor_1.jpg}
+  \captionof{figure}{Grazing Boundary Editor}
+  \label{fig:app_editor1}

+  \captionof{figure}{Grazing Boundary Editor Vertex Delete Dialog}
+  \label{fig:app_editor2}
+\end{minipage}
+\end{figure}
+
+\pagebreak
+The Android application starts up with a ``main menu" showing
+all the collar devices on a map. Immediately on this screen
+is a button that leads to the statistics screen:
+
+\begin{figure}[h]

+\begin{minipage}{.5\textwidth}

+  \captionof{figure}{Graph Screen Accessible from Main Screen}
+  \label{fig:app_graph}
+\end{minipage}
+\end{figure}
+
+\pagebreak
+Finally, the user can view the information about an individual
+collar device, complete with the collar's location, movement
+history, and current grazing area:
+
+\begin{figure}[h]
+    \centering
+    \includegraphics[width=.4\linewidth]{images/app_details.jpg}

+\end{figure}

+\section*{Hardware}
+Below are images of our current hardware assembly at the end
+of the term. These can be used as reference for the pinouts.
+The exact hardware can be found in the E-bay screenshots
+in the project archive folder.
