The Atoms and other friends are available on a monticello repository. It is something like morphic-examples. It was squeaksource I think.

Unfortunately, things in the book don't look like they do on my setup. For example, I can't work out what the key combination is to get the 'Morphic Halo'. I can get it from a menu, but not from a key press combination. Also, calling: BouncingAtomsMorph new openInWorld doesn't work. I just get an error message saying that there is no such object. I thought these problems might be due to me having the standard image instead of the Pharo by Example image. So I downloaded that image but when I call Pharo on that image: $ ./pharo ../Resources/PBE.image I just get a segmentation fault. I'm a complete newbie (but an experienced programmer in a variety of OO and other languages), so if anyone could shed any light on this, I'd be very grateful.
