Thanks for the write-up! I was a little intimidated to look into websockets before, but now I feel like maybe it's something I could tackle.
I tried out your app and I was wondering if there was a way to show filled pixels on load, rather than empty pixels that updated with changes after you loaded. So something more similar to the reddit version where a user could come in and see what has already been drawn.
Awesome! It would definitely be do-able, you would just need to connect a database. I didn't feel like doing so for this quick project, but it would be easy enough to read in those initial values! The Reddit one is actually open source if you are interested in it!
