I've been playing with gyroscope/accelerometer information in mobile browsers, I could try to put something together to showcase that...

I spoke at Ampersand Conf earlier this year about how I made a bunch of responsive Blue Note album sleeves and would love to share what I've learned as part of the side-project; specifically how CSS grid was a bit of a game changer, how I incorporated responsive typography, blend modes and a bit of background too - if that would be interesting?


PS. You can find (and DM..) me on Twitter..

Topic: Building graphical games with JS+SVG DOM

I'll run through the source code for a little in-browser game I created as a demo for the book Using SVG with HTML5 and CSS3.
In particular, I'll focus on how SVG's custom DOM methods can simplify your code for this type of graphical game, doing much of the math for you.

Examples (code & live versions) can be accessed from here:
The final version of the game can be played at

About me:

I work as a freelance web developer but I also write books & articles about SVG/web development. I am one of the editors of the SVG specifications as a W3C Invited Expert. I'm Canadian, but will be passing through Brighton & FFConf at the start of a holiday. I may be rather jetlagged on the day of the meetup, but I'm sure we'll have fun nonetheless.

Experimental, type safe, functional, immutable, null propagation / existential property access using ES6 proxies. (wow, what a sentence)

Partially inspired by immer.

const value = doing && doing.this && && !== undefined ? : 'defaultValue';

// So what if we could get
const value = get(obj, (proxy) =>, 'defaultValue');
// set
const value = set(obj, (proxy) =>, 'newValue');
// or update in a functional, immutable, and type safe way
const value = update(obj, (proxy) =>, (previousValue) => ({...previousValue, newKey: 'value'}));
