I don't have an iPhone, but I hear that for some iOS devices that local and remotely sent events do not trigger sound (and possibly the animation, pending further feedback).

If you have an iPhone and want to take a crack at it, please do.

AC:
Given an iOS user navigating to the site
When local user clicks on Ric

• should hear "haha, wooooo"

When remote user clicks on Ric

• should hear "wooooo"

At least on the iPhone SE the image is stretched vertically. I swear, Safari needs to just die b/c of weirdness like this (and also their pixel rounding).
