## Lockdown

[Lockdown](http://draeton.github.com/lockdown/) obfuscates code snippets by writing them to the canvas.
The current version is `0.0.32`. Documentation is available
The current version is `0.0.33`. Documentation is available
[here](http://draeton.github.com/lockdown/lockdown/docs/lockdown.html).

## Implementation

Place jQuery, the Lockdown script and the Lockdown stylesheet on the page:

<link rel="stylesheet" href="css/lockdown-0.0.32-min.css">
<link rel="stylesheet" href="css/lockdown-0.0.33-min.css">
<script src="js/jquery-1.7.1.min.js"></script>
<script src="js/modernizr-2.0.6.min.js"></script>
<script src="js/lockdown-0.0.32-min.js"></script>
<script src="js/lockdown-0.0.33-min.js"></script>

Once that's in place, you may replace code blocks using the `Lockdown.lock` method:

Modernizr.load([
"js/lockdown-0.0.32-min.js",
"js/lockdown-0.0.33-min.js",
{
test: Modernizr.canvas,
nope: "js/flashcanvas/flashcanvas.js",
complete: function () {
$(function () {

var $elements = $("pre.code");
