More or less, it’s been two decades of the web. At first, we just made http calls from browsers and rendered markup. Things have changed quite a bit, in terms of the frameworks we use.
Consider EaselJS, part of CreateJS (www.CreateJS.com) or KineticJS (http://kineticjs.com/) for HTML5 canvas libraries. You also can consider ImpactJS if you are interested in games, as it is focused squarely on game development.
Create a new stage, add “children” which can be Bitmaps, SpriteSheets, Shapes, or other drawings. Tell the Ticker how fast you want your render loop to go (17 means update every 17ms which comes out to 60 frames per second)

SignalR is now 1.0! You now longer have to set to “Include Prerelease” to get the NuGet Packages. SignalR used to have a home on the web at http://SignalR.Net, but that wasn’t working recently and there is an official ASP.NET home at: http://www.asp.net/signalr.
Learn from the source! This build talk is the most direct information on SignalR’s intent, goals, and future.
