That ghost disk appears when you run it on a real 128K mac as well. And so does the Key Caps crash. The about box is interesting because it is actually drawn up using quickdraw rather than being a PICT resource. And, to bring up something lost from the old forums, there's a grim reaper icon in the Finder, but I couldn't find anything in the code that referenced it :-(

Here's the google cache for the old thread - may or may not work...
