Iotas' Screen Saver
The networking features of the screen-saver require a TCP/IP Winsock
implementation (on PCs) or the Internet or InternetA module (on Acorns).
Can use any film generated by The Complete Animator (including the ones
here on our Web site).
Available for Windows 3.1, Windows 95, Windows NT (for x86), and Acorn RiscOS.
32-bit versions (i.e. all except Windows 3.1) are
network-aware: if you have two or more computers on a network,
you can get them to pass the film between them. No kidding. As far as
we know, no other screen-saver in the world does this. It even works if
one machine is a PC and the other is an Acorn.
The Acorn version is in BBC Basic and is provided so you can see how to
use animations in your own programs.
The PC versions do not come with source code; there will be a
forthcoming freeware package, the Complete Animator Programmer's Kit,
including a DLL to let you play animations in your own programs.
to download a Zip archive (122K) containing the PC version, for Windows
3.1 or 3.11, Windows 95 or NT. Click here

The traditional film to use is this
(40K) tumbling hourglass, but for some others see our films page.
PlayBack (on the PC) and !ScreenSav (on the Acorn) remain © Iota
Software Ltd., but, unlike The Complete Animator itself, you're free to
copy them, and the films you get with them, as much as you like -- in
fact, we'd rather like it to get spread as widely as possible!
The HUM1.TCA and T-POT.TCA example films in the PlayBack archive were
done by Don Slaven, who has kindly said we can give them away with this
If you make a copy of either PlayBack or !ScreenSav, please copy the
entirerelevant archive, without modifying any of it. Of
course, you're free to distribute films you've made yourself as well!
!ScreenSav is also intended as a working example of how to use
animations in your own programs, and thus you can copy or adapt any
sections of the program which you feel you need. In fact, it's not
really intended as an example of how to write a screen-saver. A
"genuine" screen-saver should in theory have a much smaller memory
footprint -- by not being in BBC Basic for a start, and by not holding
the film in memory all the time.
