Video taken on SE Belmont street while driving home on my evening commute.

1. I don't own Lennon's wheels go round and round, so it was a nice coincidence this came on the radio while I was filming cars.
2. I probably should own it, since I like it. ( downloading now )
3. This video is a nice allegory on molasses-esque driving speed in Pdx. I seriously want to maim most of you.
4. Keeping a camera steadily pointed at your side view mirror during a winter rain storm is totally hampered by driving.
5. This is for all you bokeh freaks who love tiny blurry dots for some inane reason.

The Neural Orb

Thu, 12 Feb 2009 20:29:57 +0000

130 seconds of a music visualization engine and generative drawing built in AS3 using particles and physics engine. See the whole thing here: christeso.com/labs/actionscript-3-sound-visualization-generative-drawing.asp

512 particles are released with instructions to disperse randomly throughout the scene. Variants include friction and wander. Particle location is constantly tracked and more particles are drawn at that location. These particles are sized and alpha'd according to stage location creating a "corridor".

Music visualization occurs by looping through SoundMixer.computeSpectrum and creating a ByteArray. Each of the 512 particles are controlled the ByteArray which conveniently contains 512 bytes of data. Each byte contains a floating-point value. This value determines the individual particles scale and glow.

AS3 Webcam Drawing

Tue, 25 Nov 2008 03:37:30 +0000

Expounding on my AS3 webcam motion detection experiments I've designed and built a prototype for an installation that allows a person to draw on a wall using their limbs.
The concept is to allow human interaction to affect physical space, freeing oneself from all traditional user interface. The application works by constantly monitoring a webcam, taking snapshots of each frame. Those frames are then constantly drawn to a bitmap data object. Then each pixel in each frame is monitored by comparing the pixels in the current frame to the pixels in the previous one. The difference in brightness within each section determines whether or not motion had occurred in this area of the screen. If motion is detected the coordinates of a rectangular grid around said motion is recorded and the drawing begins. To slow down the drawing I draw at the x and y coordinates of the white ball which is tweened with easing rather than drawing directly where there are points of motion.

Thanks to steve for filming and editing this video, asluv for the laser drawing class and NORTH for being forward thinking enough to encourage digital experimentation.

Tracking Multiple Objects Using a Webcam

Tue, 25 Nov 2008 00:25:18 +0000

In continuing exploration into motion tracking using flash and a webcam I've created an application that enables you to track multiple objects based on color. The holy grail of the application is of course to track multiple objects without specifying color. However, this is a good step forward and actually opens up many other avenues for use. Color, after all, is ubiquitous.

The truly useful part of the code is getColorBoundsRect. If you're unfamiliar with this function, it determines a rectangular region that either fully encloses all the pixels of a specified color within a BitmapData object, or fully encloses all pixels that do not include the color. The function returns a rectangle around the color area. You can then reference this rectangles x and y respectively.

var areaColor:Rectangle = SomeBitmapData.getColorBoundsRect( 0xFFFFFFFF, _colorArray[i].color, true );

The function is rather finicky about the depth of where the object is. Since it's only searching for a certain RGB value it tends to lose it if the lighting or the object gets too small in the camera's depth of field. To overcome this you could search for similar colors. Soulwire has written a sweet Color utility class that can aid you in this endeavor. However, searching for a range of colors will also come with it's challenges, as the more range of color you search on the tougher it will be to pinpoint the exact object you want to track.

Equilibrium The Human Mashup: A Follow Up

Mon, 24 Nov 2008 18:55:45 +0000

Equilibrium The Human Mashup: A Follow Up, originally uploaded by NymphoBrainiac.
Equilibrium: A Follow Up

Last week I had a showing at Equilibrium, the Human Mashup. The show's goal was to ask "How can art and technology and the synergy of the two address humanity's next evolutionary step?". Being a staunch singularitarian this was right up, or is it down, my proverbial alley. I built an application that allows a user to take a self portrait photograph and then draw themselves on a wall simply by using and moving their hand. The premise was to use the human as the sole interface to draw themselves, exploring the convergence of man and technology. A one day only installation, I didn't have to high of hopes for it's exposure. On the flip side, this being my first showing ever I was like a greedy 8 year old on Christmas morning, and extremely anxious to see how people would interact and respond to the installation. The methodology of controlling an interface without the normal peripherals such as a mouse, keyboard, touch screen, kiosk, or otherwise was foreign to all that attended. What transpired blew me away. The attendance, response and exposure far exceeded my hopes. I barely had to explain at all to users how to run the application. People just stepped right up to the installation and began to interact with it. They were actually learning on their own while performing the drawing. People were actually converging with the technology. Furthermore, those that were done performing their drawing became evangelists, telling those who followed them their idea of how best to use the application. At that moment it became cemented in my mind that I had succeeded in my experiment. People had invested themselves in the piece to the point of bringing out their own inner artist. Several times I stepped in to 'coach' people on how to get the most out of the motion detection while drawing their portrait. The response I got was unexpected. People took personal offense that I was pushing my artistic ideas on their own drawing. Again, success. I was also sent to the floor several times by attendees who said they had come to the event specifically to see my work which they had been following online. There were even several people who mentioned that they had hooked my work up to projectors at parties they were holding. Wha?! Seriously, amazed.

I'd like to thank several people for the night. Steve Benoit for all his help with testing the application, videography and film editing of the event. The result is the shweet movie posted above. Rachel Kjack and Adrienne Fritze from SAO and Working Artists Online respectively for their organization and inviting me to submit my work. All that attended, I met some inspirational folk. And finally, my wife Lisa for her unending support and diggin' me even when I have late night dreaded 'code eyes'.

Looking forward to the next event.

Look ma's, we're on the news!

Sat, 22 Nov 2008 21:52:55 +0000

We're on the news! Wait, I abhor the news and their ratings motivated scare tactics.

Well, anyway, Lis and I were on Portland news Channel 8 last night. Lisa is making her acting debut in some of the commercials for the city of Portland this year, and I was interviewed for an interactive installation I'm developing and installing @ 5th and Alder.

The piece is about North's work for client The Downtown Marketing Initiative and highlights this years campaign to drag the economically scared shitless consumer out of the suburbs and into the unique beauty that only downtown Portland can offer. I'd say we've done a bang up job of it.

Interactive Motion Detection Installation

Thu, 20 Nov 2008 21:04:56 +0000

Interface and motion design idea for future interactive installation using motion detection.

Words are chosen at random from a random pool of Flickr tags. The words are then broken down into individual characters. These characters are then animated based on the location of user interaction.

Picture this large. Now take that image and double it's size. Picture it large enough to where you'd have to jump to reach different 'doors'. That's how I envision it.
