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!

In addition to a number of different projects (that I will put up at some point) I have been playing with making z-projections with Imagej. Fun stuff. More here.

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.

This is also kind of blowing my mind at the moment. From the guys over at c505.

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.

The past week or so, I have been working with Processing and POVRay as part of a group collaborative project. I haven’t worked with either program before, but you can see the results up top. I use Processing to generate random shapes, which then passes them POVRay to render out. I am having to use POVRay, as that is what we are going to be using eventually to make videos.
