remembering those
green mountains way back when, now…
nothing but pixels

Dusk
I wanted to create a video that was rather abstract, but still played within the confines of time. I wanted multiple frames of the source video to be included on screen in a way where it would be hard to tell what the original movie was. Using openFrameworks I created two different settings. One captures the screen then draws that captured image back to screen in random places over top of the original image. The second draws the video to an FBO that again draws a subsection to random places. Since the FBO is not cleared old frames stay displayed until their alpha values finally get completely overwritten by new frames. The FBO is then added to an ofTexture and is additive blended with a white rectangle. In both settings the mouse controls the alpha value. I improvised between the two settings and with the alpha values. The original video was shot with my iPhone on the Brooklyn Bridge at dusk. I made the music too. Code for the video:
Glockentar
The Glockentar combines a glockenspiel with a guitar.
Each time a string is plucked a glockenspiel bell is struck with a solenoid, and a beam of light is projected across the length of the string.
The light follows a logarithmic curve in terms of it’s speed as it goes up and down the string. It starts fast, pauses for a moment then goes back down the string.
The lights are essentially rectangles made in openFrameworks, then sent to MadMapper via Syphon.
In MadMapper they are then mapped to the strings.
An Arduino is used to turn the strings into switches. Each string acts as a ground, and electricity is sent to the pick. When a string is plucked with the pick the switch is closed and the solenoids and projections are triggered.
Here is the Arduino code:
Here is the OF code:
My Own Little Universe
3D drawing using the Kinect. I tracked the closest point to the Kinect plus two other relatively close points using openFrameworks. Each point has a different color and 5 particles each that draw in the 3D space with some physics. The code is here. Zooming in, through, and around the thing is fun.
