Click on the dots to change the colors until you have a reflective symmetry across a line of reflection.
'''Did you know''' that you can share Reflection and play with up to 3 others?

=== The backstory ===
Reflections was written by Walter Bender and Reuben Caron as an example of how to migrate a simple Flash activity to Sugar.
Reflections was written by Walter Bender and Reuben Caron as an example of how to migrate a simple Flash activity to Sugar.
Refexion.swf is part of a bundle of Flash games Reuben encountered at a deployment in Central America. The game is simply a grid of squares that change color when clicked (See the figure below).
[[File:Refexion.swf.png|200px]]
The closest activity we could think of that had something similar (a grid of clickable elements) was [[Activities/Turtle in a Pond]].
We created Reflection in a few short steps:
# made a [[0.94/Notes#View_Source:_duplicate_option_for_an_activity|clone]] of the Turtle in a Pond activity
# made a [[Activity_Team/Git_FAQ#How_do_I_create_a_new_project.3F|git repository]] for the new project
# changed the [[Development_Team/Almanac/Activity_Bundles#.info_file_format|activity.info]] file to reflect the name of our new activity
# created the [[Development_Team/Almanac/Making_Icons|activity icon]]
# changed the name of TurtlePondActivity.py to ReflectionActivity.py
# changed the [[Development_Team/Almanac/sugar.activity.activity#How_do_I_create_a_new_activity_that_is_derived_from_the_base_Activity_class.3F|name of the Class]] defined in ReflectionActivity.py to <code>class ReflectionActivity(activity.Activity)</code>
# removed the buttons we didn't need
# edited game.py:
:* we made the dots cycle through four colors rather than just two when clicked
:* we removed the turtle and all code associated with moving it
:* we added a line of symmetry
:* we rewrote the rules for detecting end of game
All of this was done in less than two hours.
We then created an [[Activity_Team#setup.py|XO bundle]], uploaded it to activities.sugarlabs.org and created this page in the wiki, about one hour of work.
For Version 2, we added [[Development_Team/Almanac/sugar.activity.activity#How_do_I_implement_a_write_file_method_for_my_activity_in_order_to_persist_my_activity_in_the_journal.3F|saving game state to the Journal]], added a few more game options, and collaborative play (by grabbing the collaboration code from [[Activities/Paths]]), an additional two hours of work.
For Version 3, we added a robot help function and better feedback for when you complete the pattern.
