The repo is private. We have set up a small team (me doing Julia and JS and a friend doing design and JS) and we’re planning on having the project released in time for JuliaCon. At this point we’re not ready to release it as an open source project as all our time and effort goes into building and we can’t support it.
Plan is to release code, docs and any other info in approx 3 months time. We submitted a proposal for a 30 minutes presentation at JuliaCon and if that’s accepted, that will be the great reveal 
I’ll keep updating the progress here and we’ll release code as soon as possible.
