yeah it's hilarious what people's doodles actually end up turning in to. Everything's logged on the server, I'm planning to do a stop-motion style playback video to put up on youtube eventually.

Would love to see that, please post on HN when you do

Really glad to see that people are interested in this!

We're actually planning to write up a little blog post about our learning experience with NodeJS etc, maybe open-source the code, and then post that to HN/reddit/etc.

We've actually been waiting for a good opportunity to 'launch' it properly. Just as a fun side-project, no real business in 300lines as it stands, though we'd like to spin off a simple collaborative whiteboard app at some point.

Thanks for the feedback :)
