If you want to see the power of Etoys (and squeak) and a great talk by Bert check this video of his Squeakfest 2010 presentationhttp://www.youtube.com/watch?v=WUxMP46PM-I .
Its amazing how simple it is (once you know how ;) to create your own "tiles" and interface.
FYI, one of the things Bert does is create a "Player" variable in Etoys. I tried this in Squeak 4.2 and after creating the variable for an object in the viewer I got an exception when I tried to "change value type" - "This message is not appropriate for this type of object".

I got to watch the entire presentation yesterday. Absolutely fascinating! Lucid presentation of complex ideas. The theme (Pythogoras theorem) would be attractive to both teachers and students.
The sine interpolation may pose cognitive hurdle to some middle schoolers. Teachers could subsitute this with a lead in from the circling car project. If the car is placed in a playfield, the car's x or y tile is a good candidate to use in interpolation. The 'turn by' tile will tweak the speed while 'forward by' will influence the range.
The video "Connections (Episode 4 - Faith in Numbers)" contains a scene where the rotary motion of a water wheel is transformed into multiple types of motion to drive various machinery during early days of industrial revolution in Europe.
Thanks, Bert and Steve,
