How not to make banners

Stumbled upon this:

www.tactilesound.ru

For a long time he tried to understand what the meaning of the farting hippo was, and why every time he does this, the girl on the couch jumps :)

Then I read the title - “Tactile transducers ...” - and didn’t believe it - could this very action of a hippopotamus tactilely transform and make the girl jump? What technology has reached :)

Of course, dust from under the hooves of the animal was meant, but for some reason the associations are completely different :)
