Re: Green Screen using Etoys

Kathleen,

Thanks,  I could see this used two ways with students:

   1. In a project where the algorithm is already coded and you simply tune
   a parameter for your particular Green Screen and lighting.
   2. Where the kids themselves learn the algorithm and code it (I am
   uploading a video now to explain how the algorithm works).

I am uploading a video now explaining how the code works and testing the
whole idea out on a group of kids 10-16 where they write the code.  These
kids actually used the algorithm in a course I told them to take in
parrallel to what I am teaching  (Coursera CS101).
Now I am going to try and see how well that knowledge transfers when they
try and implement it in Squeak.
One thing I will probably do different next time is break down certain
portions of the lesson into smaller chunks.
