Byte rendering implemented in Javascript, HTML, CSS, and a bit of Canvas.

Live Demo

Very early, but this is what we use live on byte.co.

Here's a quick list of what's left to do:

• Music object
• Sound on Video objects
• "fireworks" motion effect
• Unit tests

And some things that could be improved:

• Text rendering is not 1:1 with the iOS and OS X clients. Namely:
  • The Text object has different word wrap rules when word-wrap is set to auto
  • Scaling of Text objects behaves differently in some scenarios (usually when clamped vertically)
  • The Paragraph object has slightly different vertical align and line height behavior
• Link objects have slightly different rendering than native clients, causing minor overlaps in some cases

• jQuery
• Font Squirrel for incredibly easy Base64 Webfont CSS
• Web Font Loader for font load events
• em.js to measure text dimensions
