We showed PushPull at ICLI 2014 in Lissabon. International Conference on Live Interfaces. Both, a performance and a paper were presented. The paper is available here. Thanks for the conference, it was a really great event!
Here is the official pushPull page.
We are currently working on our first instrument prototype. It will be played for the first time at the Modality event next week. More info on the state of the project can be found here.
