It has been quite a while since I created the Shared Canvas, so I decided it was a good time for an upgrade...
So here is Shared Canvas, mark 2! Well almost; it's still an early alpha and there's a lot still left to do. But feel free to have a play with it in its current state :) Currently multi-user chat and drawing is supported, and multiple rooms (with passwords) can be created.
The new shared canvas makes use more modern web technologies allowing for a much smoother and more responsive experience. You can now see drawings appear as another person is drawing, together with their name! It might be a little slow currently as this is quite a lot to ask of my little ARM-based server.
NOTE: as before, this is of course a public space, so I take no responsibility for what you might find written or drawn on this canvas!
