Daniel Hodgin, the project manager and developer David Perit, the game designer of this the team gave the background of the project. He Both the developers talked about Processing and Processing.js that both projects are Open Source and free to use and contribute to. Processing was originally developed at the MIT Media Lab by Ben Fry and Casey Reas. Processing.js is a port of the Processing language to JavaScript using the HTML canvas. Processing works on Windows and Mac, where as Processing.js works on Firefox, Chrome, Internet Explorer, Opera, Safari and mobile browsers that support the HTML5 canvas element. Processing.js does not require a plugin to be installed. This allows it to run in environments where plugins cannot be installed like mobile, business and public. As it is open source it has the ability to change things to work the way you want. There is full control and access to the development community to contribute and there is no licensing costs.
