The Neverending Drawing Machine (NEDM) is a paper-based platform that blends physical and digital techniques for story creation, the delivery of seeded, participatory learning experiences, and experiments in collaborative authorship.

It allows asynchronous viewing and physical editing of shared content at a distance. It can auto-document creative collaborations between remote collaborators anywhere in the world (with internet access). NEDM is an open-ended platform for co-creative and collaborative play. Its' design was conceived in response to the increasing popularity of tablet (iPad) apps for children. One of the NEDM's goals was to uphold the importance of real-world material exploration and messiness while leveraging the possibilities of a shared, networked, collaborative digital medium.

With the NEDM, players can collage digital and analog content. The interface maps premade digital media and newly captured analog content onto specific pages in the oversized paper sketchbook used as the primary interface. Bi-directional capturing and transmission of media to a connected creation station permit co-edition of the same page. Captured images are archived and displayed as a new layer over previous content on any other creation station, collocated or at a distance. 

Rather than a static system that lives indoors, Calliope was inspired by the portability of the pochade box and "en plein air" painting, and by Kimiko Ryokai's "World as your Palette," a beutiful effort to develop tools to allow artists to create with elements extracted directly from their immediate environment. 
In Calliope, I explored going from a many-to-many format to a one-to-one.
I shrank the size and cost by using a system of mirrors and pocket projectors, substituted the button for a pedal, freeing the hands of users, and used human-readable tags (dominoes!) which can be drawn directly onto the paper. Three new tags give it sound-recording, playback and stop-motion functionality.
