Well you could try Marshal.dump(ObjectSpace), but I wouldn't. As cool as Ruby is and as cool as Smalltalk is, Ruby != Smalltalk. Ruby is not based on images, it's source-file oriented like perl or python, and was never really meant to be dumped into an image form. Of course you could probably write an implementation of ruby based on images instead of source files.
