This video shows the synchronization of video playback with JS/CSS/HTML-driven effects. As the video plays and its currentTime property reaches given values, JS functions are fired that do the work of applying overlays with filtered background images.

scale3d() and .style.zoom tricks to make content fit a wide range of viewport sizes. It actually works pretty well.

"Timeline" view.
A few expensive image decodes and resize operations, but the page is quite smooth overall in terms of scroll performance.
I noticed in Safari that I was getting some pretty severe jank (lag) when firing the machine gun in this web-based game prototype, so I started digging.
It wasn't DOM manipulation, className changes or node removal - turned out it was cloned audio resources being freed from memory after playing, and garbage allocation interrupting the game animation pretty severely in Safari (and Webkit nightly) every so often.
Using standard HTML5 audio, you can't do "multi-shot" - each audio object is single-fire and monophonic. Thus when a machine gun fires, SM2 clones the Audio() instance to make a new object that can play independently, with its own timeline and events.
These screenshots are from Chrome DevTools. Interestingly, Chrome was less-affected by this issue despite having notably-larger GC events as well. I'm not sure how long Safari was taking, but it felt like up to 1 second in Safari 6 in some cases.
In the first case, the GC event is for 9.3 MB and takes 25 msec - blowing the 16 msec / 60fps ideal framerate budget.
In the case where audio is muted and inactive, the first GC event to happen is for 3.6 MB and takes 1.9 msec.
As Mythbusters' Adam Savage would say, "Well there's your problem!"
The solution to this is to simply create a pool of sound objects and rotate through them, if the play() rate is such that the sounds would need to overlap. While this will consume more memory (if not shared/reused by the browser) up front, it should prevent a lot of dynamic memory allocation and resulting expensive garbage collection events.
In fact, most sounds (like machine gun fire) are short enough that multi-shot is not even needed.
Maybe those guys were right about writing JavaScript more like C++ after all, static and all that.
Finally released as an experimental feature, a month or two in development: HTML5 Audio() support for my JavaScript Sound API, with SoundManager V2.96a.20100520. (Progress from the prior dev version.)
This is the first time this API has had the capability to be 100% Flash-free, and I have to say, it's a rather liberating thought. It's shown here working on the iPad; it may be playback or wifi that's a bit sluggish to get going. The Palm Pre also works, which is a good indication of where mobile devices are going with this stuff.
There are some bugs and inconsistencies in support across differing browsers and platforms, but I expect those to be ironed out over time. This is part of the reason why the feature is experimental, not to mention the fact that user testing in the real world is part of where I get some of the most, and best, bugs found and fixed. ;)
Also on the Githubs:
with HTML5 for Flash-less audio!
In the web app, select the gear icon at the top right and select Labs.
Since I took this screenshot they have added Chromecast Fireplace Visualizer.
To commemorate the fact that HTML5 has been renamed HTML and the HTML spec can now be considered a ‘living standard’
Another example from Ernest Delgado, a developer at Google who created this impressive example of image manipulation in a canvas. Note that canvas JavaScript objects can be nested.

It’s been over 20 years since Tim Berners-Lee and Robert Cailliau specified HTML, which became the standard markup language used to build the Internet. Ever since then, the HTML development community and developers now at Trendism have begged for improvements to this language, but this cry was m...

"For many out there HTML5 is nothing more than an acronym to use during some geek conversation in order to show off some pretending modern knowledge. This is probably what happened here as well at the very beginning of our recent web challenge: "...come on guys, let's buzz!!!"
Mobile HTML5 Development is extremely challenging and exciting but it can also be frustrating if we don't keep in mind problems and solutions never faced in the Desktop Web. Dealing with standards not complete yet, fragmented builds of the same product, facing both weakness and potentials of these portable devices, this is just a slice of what we are doing on daily basis in Nokia R&D.
This talk is about main technical problems, solutions, and goals achieved while we were building our online Maps application and we hope to inspire and give useful tips to anybody that is dealing with building HTML5 apps for iOS and Android."
HTML5 APIs Will Change the Web… And Your Designs
Jen Simmons, Designer
For the last twenty years, we have been creating websites from inside of a certain set of constraints—inside the limits of the technology that runs the web. We became so used to those constraints, we stopped thinking about them. But HTML5 changes many of these limits. The new HTML specs define a lot more than markup—there’s a lot about databases, communication protocols, and how websites & browsers talk to each other. It’s radical stuff that will redefine the creature formerly known as the “web page.” In this talk, Jen will walk us through the new possibilities created by HTML5’s APIs and how they will shape the web of the future.
