Thanks to fluxivity for comments. I really glad you like the blog. Please spread the word.
In terms of getting hold of these applets, you can't download them anymore as the site has gone. However, google holds cached versions if you search for stuff like "hedgehog capers". I am going to try and make the files available somewhere, I just need to work out where to host them. I don't think there should be any issues about making them available as they were freely downloadable before. I will make sure I post a location as soon as I've got it sorted.
BTW I have also contacted the original developer about the source for capers but so far have had no response. If I do get a response I will post on it.
