Superfluid interactive table
Don Miller and Calli Higgins, 2010
superfluid is a Philadelphia based site that provides social currencies that compensate real efforts, without requiring conventional money. They commissioned an interactive table that would allow people to collaborate in a digital painting at TEDx Philadelphia 2010. Attendees used superfluid business cards with fiduciary codes on the back, which were linked to ten different "brushes".
The software was created from scratch using openFrameworks.
Here is a picture of the table and preview monitor:
