There's also a keypad demo, it uses the script in the VS Wiki: https://dl.dropbox.com/u/26539256/keypad.zip (password for the lock is 1132)
Also the Myst style turning room: https://dl.dropbox.com/u/26539256/Zep_VS2.zip (to unlock the brief case its just the first digit 5)
They all work with version 3.7, I did fix a problem with the Driftwood demo a few weelks ago
