Canvas is pretty cool: https://github.com/yosoyubik/canvas There's a bittorrent tracker you can read about on the mailing list too which is pretty neat. There are a couple of folks working on supporting ship-to-ship bitcoin payments, which is very nearly to a working demo. If you haven't been on in a while, Landscape (the web client that ships with Urbit) itself is also really awesome.

So... I'm kind of curious about how this is built. Here's what I'm guessing... 1. The actual "drawing" is all the JavaScript frontend. 2. The Urbit stuff handles a few things... 3. Serving up resources (JS, HTML, etc) 4. Saving the strokes that make up the drawing 5. Communicating those to other clients 6. Communicating peer stokes back to the browser There's not many conflict issues here, and to the degree there are you can almost ignore them, so I'm assuming the peer-to-peer part is mostly just about communication. I poked through the Hoon source some, and most of it looked like wiring. Three files seem to actually do interesting things: https://github.com/yosoyubik/canvas/blob/master/urbit/lib/se... : I think this mostly sets up the server, including resources and maybe some peer authentication? https://github.com/yosoyubik/canvas/blob
Read the rest
/master/urbit/app/ca... : This seems to handle the server part that is specific to drawing https://github.com/yosoyubik/canvas/blob/master/urbit/app/ca... : I guess this is all the peer to peer logic? This is the sort of application that would usually be familiar to me. The server is serving up static files, and keeping a kind of shared log of strokes with communication across peers to share that log. But the source feels like reading cyrillic: I can't even construct a mental AST.
