inspiration from an example of homogeneous coordinates in my linear algebra book and lectures about lineartransforms.
There is a jar, with sourcecode, if you want to se it &#8220;live&#8221; or twiddle with it.

<p><a href="http://rotand.dk/AttractorWars">Strange Attractor wars</a></p>
<p>It is heavily inspired by <a href="http://kittenwars.com">kittenwars.com</a>.</p>
<p>I have been hacking away on this far to long. But expect an article with more details on Strange attractors and probably more features in the &#8220;war&#8221; application. (like top 100, biggest looser, most victorious etc).</p>
<p>Now just go and make some votes <img src='http://rotand.dk/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>I the moment I&#8217;m taking a course in Numerical Analysis, and here we were of course introduced to the <a href="http://en.wikipedia.org/wiki/Newton's_method">Newton-Raphson method</a> for finding roots. That is the method where, geometrical speaking, we take at tangent line to a function and use that to approximate the root, and keep on doing that until we reach satisfying precision.</p>
<p>Depending on where you start the iteration you get a a different root, and requiring a different amount of iterations. That&#8217;s self-evident. The &#8220;funny&#8221; part is that when searching for complex roots there are areas in the complex plane, where a very small difference in starting point gives different roots, and with remarkable difference in the number of iterations.</p>
<p><a title="Newton for x^4+2" href="http://www.rotand.dk/blog/wp-content/newtonx4.png"><img src="http://www.rotand.dk/blog/wp-content/newtonx4-150x150.png" alt="Newton for x^4+2" /></a></p>
<p>This is a plot where each root in the polynomial x^4+2 have been assigned a different color. And each point is colored according to which root a iteration starting here finds.</p>
<p>Now thats  the mathematical part of it. Now to the beautiful part or at least more fascinating part. The pattern reapeats it self, as a fractal, when you zoom in.</p>
<p>So i modified my code to zoom in, and i used a diffenrent coloring scheme where i only colored according to the number of iterations taken. This made it possible to generate a video zooming in og showing the rapeating patterns in &#8220;nice&#8221; colors.</p>
<p>Here a some videos :</p>
<p><a href="http://rotand.dk/dolly/deepZoom3.mpg">4 roots (14.6 mb) </a><br />
<a href="http://rotand.dk/dolly/deepZoom7.mpg">7 roots (50 mb) </a></p>
<p>Yes I know that its very large files, and maybe i will upload them to google video at a later time for easy viewing and less quality.</p>

			<content:encoded><![CDATA[<p>Last year I heard about the Critical art Ensemble at <a href="http://digitalfestival.dk/">digitalfetival</a>. They make concept art which is a genre that I have a very ambivalent relation to. On one hand some of it is just weird and far out for the sake of be weird and far out, and then there are gems, Critical Art Ensemble is one of the fine gems.</p>
<p>The stuff they make are relevant, questioning and thoughtprovoking. As with other concept art &#8211; it not the installation at the exhibit thats the most intriguing &#8211; but the questions it raises. At their website there are description of some of there works &#8211; enjoy <a href="http://www.critical-art.net/">www.critical-art.net</a></p>
<p>Besides Seeing the exhibition of &#8220;marching plague&#8221; I had the luck to hear Steven Kurtz speak, about Critcal Art Ensembles art and the current case. Because at the moment Steve Kurtz from the Critical Art Ensemble are facing criminal charges, they story is hard to believe &#8211; I mean that that this could happen, being charged for for making art. Heres the short introduction from <a href="http://www.caedefensefund.org/faq.html">The Critical Art Ensemble Defense fund</a>.</p>
<p><span id="more-36"></span></p>
<blockquote><p>What happened to Steve Kurtz?</p>
<p>On May 11, 2004, Steve Kurtz&#8217;s wife of 20 years, Hope, died of heart failure   in their home in Buffalo. Kurtz called 911. Buffalo Police who responded along   with emergency workers, apparently sensitized to &#8216;War on Terror&#8217; rhetoric,   became alarmed by the presence of art materials in their home which had been   displayed in museums and galleries throughout Europe and North America. Convinced   that these materials &#8211; which consisted of several petri dishes containing harmless   forms of bacteria, and scientific equipment for testing genetically altered   food &#8211; were the work of a terrorist, the police called the FBI.</p>
<p>The next day, as Kurtz was on his way to the funeral home, he was illegally   detained by agents from the FBI and Joint Terrorism Task Force, who informed   him he was being investigated for &#8220;bioterrorism.&#8221; At no point during the 22   hours Kurtz was held and questioned did the agents Mirandize him or inform   him he could leave. Meanwhile, agents from numerous federal law enforcement   agencies &#8211; including five regional branches of the FBI, the Joint Terrorism   Task Force, Homeland Security, the Department of Defense, and the Buffalo Police,   Fire Department, and state Marshall&#8217;s office &#8211; descended on Kurtz&#8217;s home in   Hazmat suits. Cordoning off half a block around his home, they seized his cat,   car, computers, manuscripts, books, equipment, and even his wife&#8217;s body from   the county coroner for further analysis. The Erie County Health Department   condemned his house as a possible &#8220;health risk.&#8221;</p>
<p>A week later, only after the Commissioner of Public Health for New York State   had tested samples from the home and announced there was no public safety threat,   was Kurtz allowed to return to his home and to recover his wife&#8217;s body.</p></blockquote>
<p>When the police realized that it wasn&#8217;t biowarfare but art he were producing, one might be quick to draw the logical conclusion : sorry for the misunderstanding, case closed. But no, it keeps rolling and Steve Kurtz is actually in danger af getting convicted and imprisoned for up to TWENTY YEARS! Its so insane, I&#8217;m lost for words.</p>
<p>Please consider supporting the defense fund.</p>
