This is the culmination of the Video Leaf sketch. (However somewhere along the way the video input part got left out.) The video projector casts a shadow on the wall and virtual leaves are aligned to the shadow. When the viewer taps the physical twig, the leaves in the drop from the shadow tree.

This piece was on exhibit Grey. Green. show.

Video Leaf // part e

download the app (Mac only)—view the code (main file, leaf class)

The color filling the brown leaf is calculated by averaging the hue of every pixel in the video frame. The color in the green leaf is just green. Hey, it’s a work-in-progress…

Video Leaf // ver E
The leaf shape is an SVG. Its fill color determined by the average color of the webcam input. The leaf veins are a transparent PNG overlaid on the SVG.

This sketch cannot run in the browser because of security issues with the applet accessing the webcam. If you are running OS X and have a webcam, you can download a standalone app of the sketch.

This is a test for a piece I am developing for a gallery installation. More details to come…

Slit-scan photos

run the sketch—view the code

How do you use it?
space bar = start a new scan
x = toggle between color or black-and-white
s = save a .tif (doesn’t work in web browser)

What is it?
I found these thoughtful and elegant photos by Ansen Seale on Spraygraphic so I thought I’d try my hand at it. Obviously I’m not a practiced photographer like Ansen.

It is basically the Slitscan example sketch by Golan Levine and Fry that comes with Processing. I just added mousePressed() events to start a new scan, convert it to black-and-white, and to save the image.

Why is it cool?
You decide.

More fun with the Video Library

watch the video—view the code

How do you use it?
Move in front of the camera. Anything that is cut off by the right edge of the camera frame will leave a trail.
What is it?
A stripped-down version of yesterday’s sketch. The mouse interactivity was just getting in the way. This is where all the fun happens.

Why is it cool?
It takes me back to the days (nights really) when I would pump all of my spare change into the copy machine to make abstract images by moving stuff around on the glass while it was scanning.

Fun with the Video Library

view the code

How do you use it?
Dance in front of your web cam and move the mouse around.

What is it?
Playing with the video capture library. You need a web cam to use this one. It also can’t be run in the browser. There is code built in to use the MovieMaker class too, but it is commented-out. To record a Quicktime movie you will need to uncomment the //mm.addFrame(); line.
