Just installed it. A very creative but frustrating package. As with too many of these things, one must be able to read and that in English (or a few European languages?). Fine print abounds in what at first looks like a very sparse UI. The program abounds with objects and widgets. Some very creative and versatile, others frustratingly crude. Graphic objects like squares cannot be resized (nothing stops one from reprogramming them and then dutifully uploading the scalable versions for others to enjoy--smalltalk was once the rage.) Smalltalk 80 is, well, 26 years old. Before Unicode so is incompatable with mutlingual keyboard choices. No Hebrew for my daughter, not in UI and cannot type it in to text objects either. Truetype fonts (newer than smalltalk80) are beatutiful but they are also Unicode based nowadays. I think most kids would enjoy trying various widgets but run out of patience doing anything more with them. Most adults would as well. A model (allbeit not an audio app) for a program sutiable for children but versatile enough to be of interest to their parents as well: Tuxpaint. This one is superb and is also in use in many schools. (Also needs more languages in the UI!)
