TOTALLY SUPER DUPER NOT MY WORK! Trying to illuminate how FizzyText (seen here, source here, isolated from dat.GUI dependency here) works. Original appears to have been written by George Michael Brower.

In the original, which I find brilliant:

• Solid black text is drawn onto an invisible canvas, from which it gets bitmap data
• The bitmap data is read like a collision detection array, where black means "you're on top of text" and white means "you're not"
• Particles of size r=0 are randomly spawned on a visible canvas
• The particles grow if they're on top of a (non-rendered) black pixel, and shrink till they disappear if not
• When they shrink to r=0, they respawn randomly somewhere
• The particles follow a Perlin noise flow field, a very sensible and fluid kind of random movement, in which nearby particles

DEPRECATED

I think most of this stuff is now depracted. Looks like C++ is the only realistic way to go for implementing WebIDL bindings in Gecko. That's unfortuante, because if you are a JS dev, learning C++ can be challenging (though worth while! it's a fun language.)

Implementing a JS-based WebIDL binding in Gecko

This provides a gentle introduction to implementing a WebIDL interface in JavaScript. Once you are done, you can refer to the MDN Wiki, to add more advanced things.

Before you start

We would encourage you to first build a simple prototype version of your API in JS. Going through the process of creating a WebIDL is fairly straight forward, but if you screw it up you will need to recreate a whole bunch of files, etc. As such, it's much easier to make sure you have your API in a good state before attempting the steps below.

This does NOT work on Raspberry Pi 2!

0. Obtain a 8GB (or bigger) SD Card
1. Download disk image from http://janos.io/builds/fxos-pi-gpio.img.zip and unzip
2. Put SD card in your computer
3. Find out where your SD card is mounted (BE REALLY SURE ITS THE RIGHT DEVICE, IT WILL BE WIPED COMPLETELY!!!), f.e. /dev/disk5 on OSX
4. On Linux, run: sudo dd bs=4M if=fxos-pi-gpio.img of=/path/to/your/disk
5. On OSX, run: sudo dd bs=4m if=fxos-pi-gpio.img of=/dev/rdisk5 (do rdisk, not disk here!)
6. When it's done put it in your Pi and start up
7. The demo's are wired like this: yellow LED on GPIO2, red LED on GPIO3, button (wire it as pulldown) on GPIO26.
