Google new UI: The cool calendar create button

News about Google+ is everywhere. People are surprised with the Google+ clean user interface and the new color theme. At first I was taken a back by the black toolbar on the top of Google search page, but after seeing the calendar new interface I clearly see the whole theme and the role of the black toolbar with the new color scheme. What I am excited about is the new "Create" button of the Google Calendar. The color goes well with the black toolbar as well as the gray header and the coolest thing is that, it is an actual button. Actual button because it emboss subtly when you hover on it and it depress subtly when you click on it. It looks clean, elegant and really feels like button, unlike those in Amazon and Yahoo mail which look like a dud.
