+===== Assignments =====
+==== Part 1: Blog Posts - All of them ====
+  * Write Blog Posts about
+    * **Projects** - Each project should get it's own post. Screenshot, link to demo, description. You are building a portfolio. Don't forget to link your Design Docs from now on!
+    * **Stone Librande** - Write about what you thought and learned about Stone's presentation. Make sure to thank him at the end. Put in some image. I will send these posts to Stone as a thank you.
+    * **Design** (optional) - Skim through the design book. Write a post about the main principles of design. Make sure to talk a little bit about color. Put in some image. Spend no more than 10 min on this.
+Double check your links!!
+----
+==== Part 2: Programming (TEAM) ====
+(Afternoon groups listed at the top)
+Mousey the mouse needs to sort his cheese stick collection. There are 20 cheese sticks of different lengths in random order. Please help Mousey write an algorithm to sort his cheese sticks in Processing. Mousey lives far away, so Mousey will have to visit your blog to learn how to do this himself.
+First: Make Mousey a design doc based off of what you've learned. Design doc can only be 1 page. It should be in the final Github repo with the [,doc] and the [.pdf]. This doc will explain the design of your prototype. Mousey likes more pictures and less words.
+Your design doc must explain the runtime of your algorithm to Mousey: http://bigocheatsheet.com/
+Next: Make an array of integers in some random order, like this in Processing:
+<code java>
+int[] cheesesticks = { 90, 150, 30, 22........ };
+</code>
+or you can do it manually:
+<code java>
+int[] cheesesticks = new int [20];
+cheesesticks[0] = 90;
+cheesesticks[1] = 150;
+cheesesticks[2] = 30;
+</code>
+.... Do whatever makes more sense to you.
+Now pick your favorite sort and sort those numbers. You will need to create a swap function.
+Once you can sort them, try to draw them on the screen and animate them. Like these: http://www.sorting-algorithms.com/
+If you finish this early, you should either try another sort OR.. help Mousey learn the http://en.wikipedia.org/wiki/Sieve_of_Eratosthenes.
+Try to get your project blog online, if you have time. Also, don't forget to link your design doc in the blog.
+----
+==== Part 3 - JS Platformer ====
+Cookbook! You know what to do.
+Additional Challenge: Make your own SPRITES! This part is fun :)
+(Help Mousey get his cheese)

+----
+==== Part 4 - Make Ups ====
+Use the rest of the day to fix any old projects up from the previous labs.
