The real-time collaboration of this looks cool. I don't understand what the dinosaur (or now penis) has to do with it. I can't make those colors... where did those come from?
I made something called Sketch-a-bit (for Android) [http://sketchabit.adamsmith.as/] that's a charcoal-like sketching interface that has you start from someone else's drawing instead of a blank canvas. It's been alive for about 3 years and it's interesting to trace back the history of awesome sketches (http://sketchabit.adamsmith.as/master.php) and see how they evolved. Collaborative along the long-term dimension instead of all in parallel.
Here is an interesting experiment - create a "nice" looking rectangle of one solid color. See how long you can go before someone "maliciously" puts a red dot in the middle of your perfectly OCD constructed rectangle. Human nature + anonymity...
It's an iOS app I made that lets you make pixel art and see artwork other people are making at the same time. There's also a little websockets powered view on the website of what people are making.
Well it didn't take long, but it seems it's already been scripted to blast porn image in there. Would it perhaps be a good idea to have a per user pixel throttle?
I'm loving abusing this! The only problem is there are too many people trying their scripts at the same time, but it's really cool you left it completely hackable!
for (i=0;i<60;i++) { for (j=0;j<60;j++) { firebaseCanvasData.child(i+':'+j).set("rgb("+(255-i*2)+","+(255-j)+","+(i*j)+")") }}
Edit: Ok, definitely too many people abusing it...
Yip, Right Bottom Corner, a guy even righted HN. This reminds me a lot of the first online Minecraft server, keeping in mind Minecraft was a lot more advance.
The only problem with a canvas like this is griefing.
