New Chrome autoplay policy blocks lissajous context

[j6k4m8]

New users in Chrome are likely to encounter the following:

context.js:7 The AudioContext was not allowed to start. 
It must be resumed (or created) after a user gesture on the page.

(anonymous) @ context.js:7

This is a result of changes to the Chrome audio policy.

If you encounter this issue, you can re-enable the lissajous web audio context with:

context.resume()

before beginning your performance.
