Hi, Karl - With your permission, I'd like to put this Etoy on the Squeakland site for further sharing and distribution. What would be really helpful to novices taking a look at the project would be if you could add some text explaining what you did and what the elipse does and why it does it. (What is the purpose of the blue rectangels in the holder?) It would be great to have a little introduction and explanation about the parts of the Etoy. Would you be willing to add a bit more info and share another version that we could add to the Squeakland website?
I'm working on it. The blue rectangles in the holder holds instance variables with former x and y values of the ellipse. Each time the ellipse moves forward it adds a new rectangle to the holder. That makes the backtracking possible. Etoys sure are fun :-)
