Here's my latest version.
EDIT: I've added the ability to play audio accompaniment while flying thru space, but you may have to supply your own sound files. And you'd have to change the program code to refer to your own files, unless the filenames are exactly the same.
I've attached a help file below.
=== IS IT OK to upload copyrighted material here? If not, I'll have to remove the audio files and resend the archive. ===
EDIT: I changed the code to check the Audio folder for available files, so that the user can place his/her own sound files there; then my IDE closed unexpectedly. When I reopened it, no auto-saved file was offered, so now I have to redo all that. In any case, one of the audio files I had included is CREATIVE COMMONS, so I'm leaving that one in, and I don't care what anyone says about that. Ciao for now. I'm gonna work on some SketchUp models for a while instead; that's much easier when I can't concentrate, which is quite often.
