What doesn't work? Link, page, CSS?

Everything seems to work for me. Firefox latest stable release

[Normal_gaussian]

I get a static image in firefox - https://github.githubassets.com/images/modules/site/home/glo...

I get terribly jittery rendering in chrome (despite being on a powerful desktop that is doing nothing else).

Like Normal_gaussian, it was just a static image. Works for me now, though. No idea what changed.
