!MellowOut/!Help
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

ScreenSave
==========
Phosphors need coffee breaks too, you know. Let your monitor chill
with Mellow Out.
When nothing's happened on the desktop for a while, Mellow Out
will give your monitor a change of scenery... and if you don't like
plain black scenery, you can choose what scenery to change it to by
dropping an IotaFilm file (type C2A) on the icon bar icon.
Other features
--------------
Choose Delay->Now! from the menu to see the film in action without
having to wait around.
If you want your film to waft around the screen interestingly,
have a look at the Features submenu where there are three varieties of
wafting. (Delta films can only be played centred, that is, waftless.)
If you want your ears as well as your screen saved, turn off
Features->Sound.
If you want the film played flat out, turn on Features->Fast
(Otherwise the frame rate specified in the film is used).
Choose Clear from the menu to make Mellow Out use a blank screen,
which is not only fashionably Spartan, but also means Mellow Out uses
as little memory as possible - films can be rather large.
Choose Save as Default to save
- the currently chosen film
- the currently chosen delay
- the current Centred, Flying, Bouncing or Wandering setting
- whether Sound is enabled
- whether Fast is enabled
as the defaults for when Mellow Out is next loaded.
Mellow Out is in BASIC, so you can load it into an editor and
check out for yourself how to use IotaFilm files in your own programs.
Mail demon
----------
[Technical:] If Mellow Out receives a Wimp message number &81EFF,
with the message data (from block+20 onwards) a zero-terminated sprite
name, this sprite is also plotted wandering about the screen until the
screensaver is next de-activated. This can be used to give an
indication of system status at a glance; for instance, an email
application could send this message with a "mailbox full" sprite when
mail arrives. The sprite must be in the Wimp sprite pool, it must have
a palette, and it cannot be a 256 (or more) colour sprite.
