I had to do something like this for a "family day" event. The trick is to combine a trail file and a mapkey.
Create a mapkey that runs your trail file. At the end of your trail file, include a sequence to run the mapkey again. Mapkey starts trail file, trail file starts mapkey, endless loop. You'll have to kill the session to stop it.
The config.pro option TRAIL_DELAY slows down trail files, but don't use it. You can't set the delay to less than 1 sec, which makes the playback painfully slow.
I had a couple of different mapkeys to slow things down, all were "OS Script" mapkeys that run external programs. A couple ran a script that went to sleep for 1, 2 or 5 seconds. This would allow someone watching a drawing being created to see the final result, before blasting onto the next task. The other mapkey ran a program to display a predefined message in a dialog box, which usually occurred during a pause. Let's the user know what's going on or about to happen.
Definitely many other ways to do it .... could just record a session to a movie or flash file.
