Mrmr (http://ecumedesjours.com/Mrmr/) is an ongoing research project to develop a standardized set of protocols and syntax conventions to control live installations and multimedia performances via mobile devices. The project was begun by Eric Redlinger, then researcher-in-residence at the Polytechnic Institute of NYU's experimental media center. Mrmr enables you to use ordinary cell phones and tablets as controllers in audio-visual performances, or to participate in interactive museum exhibits, or to use your mobile device in the place of the mouse or trackpad from your full-size computer. It also makes a great, free OSC controller for Max/MSP, VDMX and other VJ/DJ software. Key elements of the Mrmr project are: • create your own interfaces using only a text editor • multiuser by design / client peer-to-peer or client-server models supported • open standards (zeroconfig/bonjour/mdns, OSC) • dynamic interfaces: widgets can be reconfigured 'on the fly'

L.E.D. Lab is the quickest, easiest, most powerful way to drive your LED display! Custom programming is no longer required to get up-and-running. It is ideal for artists, professional display designers, architects, VJs, lighting designers, hobbyists, and anyone wanting to add a little animated color to their sculpture, art car, home, business or wardrobe. L.E.D. Lab allows you to create a list of Scenes, which can be played back in order or shuffled. There are currently two kinds of Scenes: ● Pictures Scene - A montage of still images, videos, and live camera feeds is designed. The position, velocity, rotation, size, and coloring of each picture can be animated. You can use your own photos and videos, and the iPad camera. Rendering to odd-shaped displays is made possible with photographically-generated map files. ● Strips Scene - Particles of color are sent down each strip. The velocity, hue, saturation, and brightness of each particle can be animated. Other features include: ● Music - Create lists of Tracks. Each track plays a song from your music library, along with any number of Scenes. You can elaborately choreograph a song, or let the Scenes play in random order. ● Audio Reactivity - Any animatable parameter may be controlled by the amplitude of audio in a specified frequency range. ● External Control - Any animatable parameter may be controlled by MIDI, DMX, ArtNet, or OSC. ● Color Keying - An image, video file, or live video feed can be made selectively transparent, making it easy to mix in with other images. ● Tiling - Any image, video file, or live video feed can be tiled in any or all directions, with adjustable spacing and fade-out. ● Display Modes - Editing can be performed with or without the LEDs connected. The editing UI can also be hidden, allowing operation in a "kiosk" mode. So what kind of LED display can you make with L.E.D. Lab? Some Examples: http://ledlabs.co Any iOS device can be used to play Scene Lists. An iPad is best for full editing. L.E.D. Lab works with the following LED controllers: ● PixelPusher (our favorite) ● Art-Net ● sACN ● DDP/Minleon/TekLights ● RGB-123 ● FadeCandy/FCServer ● OpenPixel It can also display to an external monitor or projector, serving as a VJ app. Extensive help information is provided for the rich user-interface: ● Help Explorer - Displays help text for any knob, slider, button, popup, list, or view inside a magnifying glass you drag around the screen. (See this in the last screen shot.) ● Help Topics - Little chapters to read about some of the more detailed functionalities. ● Help Tutorials
