I live in Moscow, and I just found out there's a museum of Soviet era arcade machines in the city. I am going to see this shit as soon as possible. Ignore the guy's broken English, look at some of these whack machines.
Seriously he's playing a periscope game or something, and then hitting the buttons on a thing called ВИКТОРИНА (Viktorina) which I understand to mean "quiz game", but it looks like it was ripped out of the reactor from some sovok power plant. Some pictures and stuff at the museum's website http://www.15kop.ru/
