Is there an application where the user has to wriggle his eyebrows to play a game or something?

Because I just saw this guy on the train do that for 15 minutes straight while staring intently at his smartphone.

I am completely wigged tonight. Went for an overtime assignment and got back home at 10-ish. Only had five hours of sleep last night. (Why? Coz I stayed up reading some sexy doujinshi, ha)

Gonna get some early rest then. Toodle-O.
