1. About Scratch overview and video demo. Fun video is 1 minute 37 seconds long. Watch it!

   With Scratch, you can program your own 
             interactive stories, 
                    games, and 
                           animations 
                                  and share your creations with others 
                                               in the online community.
   Scratch helps young people learn to 
               think creatively, 
                       reason systematically, 
                                 and work collaboratively - essential skills 
                                                for life in the 21st century.
   
   Scratch is a project of the Lifelong Kindergarten Group 
                       at the MIT Media Lab.   It is provided free of charge.
   

2. Scratch and dancing cats - drawing a square with cat instead of turtle. SCRATCH.MIT.EDU

3. Scratch Resources and links and examples.

4. New Example created on IEE and IE: Scratchy the Cat Dancing tutorial results.

5. Tri to use Scratchy the Cat and a Cowbell as the actors to teach triangles RIGHT: Scratch and NetLOGO turtle graphics triangle terminology
   Legs, Hypotenuses, Right Triangles, where is Waldo in Cartesian coordinated 2D space?
   Needs more cowbell, but has some at least!
   Adjacent leg, Opposite leg, and Hypotenuse of one of the acute angles or a right triangle.
   SOH, CAH, TOA acronyms... Coming soon to our NetLogo lessons.

6. Here is a JOKE or POEM example done with Scratch. Have you heard this joke/poem before. I found it in my STANTZ22 account.
