"Round" videos on Youtube

We all got used to the rectangular player, even got used to the vuvuzelas that were built into the player for the duration of the World Cup in South Africa (they could be turned off). But now Youtube went further.
Meet: round rollers. (Unfortunately, the code is not issued to them and I cannot insert one of them directly here)

This, of course, is done only as an advertising campaign, but the idea itself is cool. Who knows, maybe in the future everyone will be able to choose between players.

Thanks to Evgeny Kozlov for sharing the information.
