Drawn Together was an interactive art installation done in collaboration with artists, OpenEnded Group. Participants could actively engage in a collaborative 3D drawing interaction with a computerized modern, drafting table.

Contribution: I was a designer and fabricator on this project. I participated in ideation & prototyping of the drafting table where we utilized 3D models and 3D printing for rapid prototyping. I also helped design/install the hardware configuration and used CNC Routers to fabricate physical components for the installation.

Arts@Tech is a new initiative at Georgia Tech that seeks to bring the worlds of Art and Technology together.  The Arts@Tech website serves as a portal for those in the Georgia Tech community to find, seek, and post their art-related work. Visit the Arts@Tech Website

Contribution: My role for this project was user experience designer and web developer. I conducted a wants/needs analysis and competitive analysis prior to starting the project in order to get a sense of what my client was looking for, what our target audience would respond to, and what other similar sites were doing.
I developed the site using drupal as a majority of Georgia Tech's sites use this content management system. Copy and images for the site were provided by GT Institute Communications.

Lines of sight are important. They visually tie the two sides of a seam together. Boundaries do not only divide. They also join things together. Located on the historical boundary of North Avenue in Atlanta, Georgia, my goal was to try to (re)sew two opposing communities–separated by economic/social/cultural/racial/historical barrier–together at …

Contribution: I was the architect for this project and was inspired by the idea that North Avenue in Atlanta is a metaphor for the seam.
The result was a mixed-use development consisting of townhouses and apartments with a retail greenhouse.
