This can be also achieved with Fractint, by using the evolver feature. I don't have it installed right now, but I remember a post a while ago with the specific instructions to get a picture just like that one.
That was probably one of my posts from ages back when I was experimenting with the prototype evolver. Actually if you run the demo.bat file that comes with fractint and select the evolver demo it steps you through it and goes into how to zoom the parameter space to produce ghostly spirals etc. I do like the effect that resizing a highly mosaiced (is that a real word?!) picture has as shown on your website Marc, it averages out the confusing high frequency detail in all the smaller images to produce that nice ghostly fuzz.
Somebody in the list will probably find out the required evolver settings, in a matter of microseconds.
They're in the help docs for the evolver :-) Actually all this reinvention of the wheel reminds me of a thought I had the other day, what fractint could do with is a central repostiory for users tricks and tips etc, a good format for this would be the form of a wiki wiki web. Whassat you say? Wiki wiki what? For those who haven't come across this remarkable form of user supported website go have a look here: http://c2.com/cgi/wiki?WelcomeVisitors http://c2.com/cgi/wiki?OneMinuteWiki or here for an example of a more stylish wiki format which forms a resource for writers of modifications for the game Unreal Tournament (you'll find some stuff in there from me, masquerading as 'zedsquared' ) http://wiki.beyondunreal.com/wiki/Wiki_FAQ It's basically a website that *anyone* can edit whenever they want using only a web browser. The markup used is simpler than HTML and the wiki server does the rest. A common argument is that leaving it open to all leaves it open to abuse, this is true but as long as someone looks in every now and then the abuse can easily be undone as the server stores previous versions of the wiki pages which can be restored at the click of a mouse by the administrator, it's so much easier to repair damage than it is to actualy edit it in that it all looks after itself. We could prime the fractint wiki with a copy of the current docs and let it run from there really. So what do you folks think? Has anyone the hosting ability to set one up ( Damien? ) Failing that we could start a fractint section of the wikipedia. Cheers, Robin.
