Hello Joop,
First of all thanks for your mails with the java programs, of course I have installed and running some of them.
But when I've seen the Jsoko, and I've gone to download it I've seen 62Mb.zip, and out of curiosity I have the Trashman from Carol Soft, which is the same game for OS/2, and occupies 120K unzipped. Only is 607 more times size.
Long live the progress !!!
