If you missed the Online Celebration, you can still watch it. So pour yourself a mug of Sbiten*, sit back, and enjoy the show.
* Sbiten is a traditional Russian hot beverage made from honey, water, jam, and various spices. It dates back to the 12th century, when it was made in copper samovars by sbiten makers who sold it on street corners. The name sbiten is derived from the Russian sbit, meaning to beat, referring to the act of pounding spices and herbs in a mortar. (Source)
