+## Motivation
+
+- Some tasks are easier with a GUI
+- Seeing a lot of information in one shot
+- Easier for non-programmers
+- Easier to share
+
+<!-- #endregion -->
+
+<!-- #region slideshow={"slide_type": "slide"} -->
+## Why ETS?
+
+- Mature
+- Easy to use
+- Design promotes reusable code
+- Largely declarative UI
+- PyQt/PySide and wxPython support

+## What is ETS?
+
+- Enthought Tool Suite: https://docs.enthought.com/ets
+- Open Source
+- Packages
+  - Traits: Python object attributes on steroids
+  - TraitsUI: Easy GUI-building
+  - PyFace: Low-level GUI components
+  - Envisage: plug-in application framework

+## Goals
+
+- Start with simple Python script
+  - Detect faces
+  - Extract Image metadata
+
+- Build a full-fledged desktop application
+  - Easy to use UI
+  - Learn a little MVC
+  - Design application to scale
+- Share the application with others

+## Schedule
+
+- Step 0: Python script
+- Step 1: Using Traits.
+- Step 2: Basic GUI using TraitsUI
+- Step 3: PyFace application: tree navigator
+- Step 4: More features
+- Step 5: Installer

+## Basic Python script
+
+- Uses: `PIL`, `skimage`, and `matplotlib`
+- Detects faces in a given image
+- Look inside ...
