I have been meaning to post this for awhile. Among other things, I recently wrote a Processing sketch that uses Carnivore to sniff the packets on a local network, then does a whois search on the IP address to look up the physical address attached to them. The sketch then displays the address, and plots it on a map. The more packets that come from a location, the brighter the dot.

In this iteration, I just used the Arin server, so it’s just for US addresses. This also limited me to a US map (which I stole borrowed from one of the examples in Ben Fry’s Visualizing Data book).

Since this is a Processing sketch, I could have done an embedded applet for this entry, but Carnivore requires some changing of permissions on the local machine to do the packet sniffing. And well, you can’t do that from a web page.

The code for this is here, but I will warn you now that it is undocumented. And it comes with no warranty, use at your own risk, etc. Enjoy!

Just playing around.

And the image above links to the Vimeo page where the video is hosted, as they don’t allow for embedding of HD video yet. And the lower res completely destroys the inside of the sphere.

Time Slice from Ian on Vimeo.

Each horizontal line corresponds to a horizontal line of a frame from a video sequence. So, this is 360 pixels high = 360 frames from a sequence. What is shown here are the frames scanning down, so that the first frame of this are all of the first lines of the frames, the second frame of this is the second line from all of the frames, and so on and so forth.

Made with Processing.

One more with the glitch process.

Another iteration of the glitch program that I have been working on, this time as an animated gif.

I wrote a little Processing sketch that randomly fucks with the byte data of image files. The result is glitched image files. Lots of them. That I can animate. Click on the image above for the movie.

I will hopefully have more iterations of this soon. I kind of like this idea, going along with some previous ideas that I was working with, but from a different direction - that of manipulating the data directly, as opposed to creating the image of it. Let’s see where this goes.

Here is a test render/animation of some of the things that I have been doing lately. Click the image to view the video. The link might take a while to load, its about 12megs or so, so give a sec. But it only took about 12 hours to render 30 seconds of footage on my little iBook G4.

If you are interested in the source code, let me know and I will send it to you. I would post it, but I have been constantly working on it and tweaking it, and by the time I post it, I will have made some change to it. So just let me know and I will pass it on to you.
