Is nice to be back! :)
I have been enjoying your projects and documents in the community even
if I have not being so active for a long while. In fact I'm sharing your
projects with my students and other people here:
And I will share you and your student's Miró projects with my
interactive art teacher also. Now I'm looking something more complex and
tile programming doesn't give me alpha channel handling so I need to "go
under" etoys to use Smalltalk directly and hope for better luck.

> It is good to hear from you!
> Your question about images fading is beyond me but I have had some success using scale factor increase/decrease and show/hide to make an effect easier for me and my young students to do.
> Since your topic is art, may I mention a recent student project? My students looked at paintings by Miró and used Etoys to create new paintings, dynamic collages, puzzles, and games. Maybe the art teacher would like to see them.
> My students spent 4 or 5 class periods on the project starting with looking at about 100 paintings I cut from a book. They chose their favorite and decided what kind of Etoys project they would make. They have been smart using Etoys tools like copy and re-size, and objects and layers of objects to achieve Miró effects. It was a study in depth that they enjoyed and when you look at the whole collection you can see the influence of the artist. When we looked at the finished collection we had some very good discussions about his style, colors, and motifs. http://etoysillinois.org/library.php?tags=Mir%C3%B3%20Inspired
