For example, the stuff in Google labs (gmail) has had some silly things like don't hit send when you're drunk but sometimes very useful features which may be considered unorthodox like "Gmail telling you when it thinks you wanted to attach a file but forgot".
It's something I wouldn't generally associate with a very corporate design but here they are wanting to add another silly feature and who knows how it will turn out? Maybe it will be super useful and then all the other companies will start to copy it.
But the thing is they're inventing new ways that really don't fit your product development roadmaps. I really like that about them.
