Tunnels no Minasan no Okage Deshita - honestly

In Japan, they call it Tunnels no Minasan no Okage Deshita. You'll find it on Youtube as Japanese Human Tetris. I prefer Tunnels no Minasan no Okage Deshita, because, even though I don't understand what it means, I even less understand the Tetris connection.

The game is wonderfully easy to understand. All you have to do is watch it for a minute or two. When two or more people play it, it becomes a test of teamwork worthy of ballroom dancers. It's funny. It doesn't really make people look embarrassingly silly. It seems reasonably safe. And it invites real skill. The challenge itself is as mental as it is physical - trying to anticipate how to position your body so it will fit through the moving shape. And it makes for great viewing. Worthy of all the attention it is receiving on the net. Worthy, even, of yours.
