<#268#>Hiebeler:<#268#> Quite some time ago, I started trying to do an X11 version in my rare spare time. I got as far as having the very simple basics working, so I could display a 2-D image in black&white, load a rule and image, and run. But very little else was in there, and I never get time to work on it any more. Also, I don't know anything about doing colors in X11. So I can't really say whether an X11 version will ever be released. <#269#>George:<#269#> In case anyone is interested, I have written an X11 version of Cellsim, which runs in black and white. It has not been extensively tested, as I have not had time to work on it, but if anyone wants a copy, I'll fix bugs as they come up. %
