Velocity NY is Coming!

O'Reilly's Velocity Conference is quickly approaching -- it's September 15-17 in beautiful New York. As a follow up to last month's post, I wanted to make sure people knew I had 3 more tickets left to give away to this epic front-end performance conference!
In my last post, I asked for links to awesome performance-related articles. I learned a ton and I hope you did too! This time I'm looking for something a bit more interactive! In the comments below, please post a link to an awesome demo. Whether it's a CSS animation or a canvas/WebGL masterpiece, I want to see something epic!
If you entered via the previous post, your entry will be put in the drawing for subsequent ticket giveaways. If you don't want to chance it and want to get a 20% off discount to the conference, use code AFF20 after clicking this link!

![Detect DOM Node Insertions with JavaScript and CSS Animations]()
I work with an awesome cast of developers at Mozilla, and one of them in Daniel Buchner. Daniel's shared with me an awesome strategy for detecting when nodes have been injected into a parent node without using the deprecated DOM Events API.

Zooming in and out on this periodic table while switching between table, helix, sphere and grid provides such an engaging experience for the user. You may even discover elements you hadn’t heard of by toggling between the different views.

Mozilla’s work with Epic in porting the Unreal 3 engine to JavaScript always impressed me. Having a hard time finding the actual Citadel demo on my phone but there’s a good review with screenshots here: http://www.webgl.com/2013/05/webgl-game-demo-unreal-engine-3-epic-citadel/
