I was working on an HTML5 canvas pixel editor at some point. It was rather frustrating dealing with the Retina display, blurred edges, and anti-aliasing. I'm curious if this situation has improved at all.<p>See here for more info:

Here's another pixel editor, but this time made with ClojureScript and Om (React-based framework).<p><a href="https://jackschaedler.github.io/goya/" rel="nofollow">https://jackschaedler.github.io/goya/</a>
Any interest in packaging a portable version in PortableApps.com Format? I've already done a Launcher that handles node webkit for 2048 Portable. I can help you with a Windows icon and installer if you're interested as well.
