I tried out the zooming capability (nice) but it seems like your stroke width does not change in response to the zoom level (at least not in lock step)? So the redness in the lady's dress changes as you zoom. Isn't that a problem?
Keeping "real" thickness slows down rendering by a factor of 1.5-2 depending on browser used. Images look better though. I'm not sure what users want at this stage of the project. Perhaps a toggle?
Thanks, didn't know about bigpicture.js. The whole idea isn't that super new.
Not sure if I communicated it across: Writelive drawings are always updated in real time. Think shared whiteboard. Co-drawing / co-writing. Currently you can only view via web. Drawing is limited to Android - drawing without a pressure sensitive stylus offers bad experience anyway.
