I ran across this giant, slightly electric version of a pink cherry blossom tree a few nights ago, just outside the Fuji TV headquarters in Odaiba. A pretty stunning sight and it seems the tree serves to promote a few tv shows, with a twist. Apparently people download an app, shake their phones and the more they do it, the more the tree lights up. Clever. And engaging too – when I was there people were shaking their phones like crazy, and snapping pics, excited as ever.
