We are going to make our final call for authors at the OpenGL, WebGL, and Mobile BOFs at SIGGRAPH. In order to give people just hearing about the project enough time to submit, we are pushing the submission deadline from August 15th to August 25th. We are keeping the rest of the schedule the same. Christophe and I have been staying on top of the many great proposals we have received so we are confident that we can select authors in one week (by September 1st), but we would appreciate you submitting your proposal sooner than the 25th if possible.
The submission instructions are still the same, just use this example proposal.
