(via How to Make Moss Graffiti: 6 Steps (with Pictures) - wikiHow)

Moss graffiti, also called eco-graffiti or green graffiti, replaces spray paint, paint-markers or other such toxic chemicals and paints with a paintbrush and a moss “paint” that can grow on its own. As people become more eco-friendly and environmentally aware, the idea of making living, breathing graffiti has become a more green and creative outlet for graffiti artists. It can also be considered another form of guerrilla gardening.

(via Control)

Control enables users to create their own interfaces for controlling musical, artistic and virtual reality applications. It is built on top of the PhoneGap project and allows users to define their interfaces via JSON files. The big advantages of Control over other touchscreen control apps are as follows:

-Outputs both wireless MIDI and OSC
-Widgets are capable of being scripted via JavaScript. JavaScript (when interpreted by Apple’s WebKit engine) is allowed to be used by apps in the App Store. The ability to add scripts to widgets adds flexibility to interfaces that other applications can’t provide
-Access to Accelerometer, Gyro and Compass (in applicable devices) with control over the update frequency of each on a per interface basis. -Support for microphone and video camera input to be added shortly
-Interfaces can be dynamically pushed to the phone via OSC. This allows, for example, different interfaces to be presented to users contextually in a virtual reality environment or for different interactive pieces during a musical performance.
