Update: with a few bits filled out, the source could be build, and morpa has made it available here
. Some information about the history can be found here
You will need Megamax to compile it, but a pre-compiled program is also available in the release directory. Feel free to try it out! Although the main purpose of his project is to preserve the source, some smaller bug-fixes here and there can surely be made (and maybe i've overlooked something).
Note that, unlike the ancient version 2.07, this version does not have a gem menubar anymore, and you have to pull down the menu in an amiga-like fashion by moving the mouse to the top of the screen and right-clicking on it. Also note that the program still only runs in ST-low resolution.
Also it seems that the source is Atari *only*. Some ifdef's for Amiga are there, but some other parts seem to be lost. Maybe some amiga user can fill in the missing bits.
If you know some existing animations that were made by it it would also be nice if they could be added to the archive.
