Something is weird with this demo. I was hearing yanny the first time, slided towards laurel, which I heard, and sliding back in the yanny direction, I can't hear anything else than laurel anymore, even at the rightmost yanny position. However, if I listen to the samples at https://twitter.com/xxv/status/996462632998711297 https://twitter.com/xxv/status/996462632998711297 I can hear yanny.
