#Sundance on Instagram: Day Five

We're at the midway point of the Festival and the quality—and quantity—of #Sundance photos on Instagram is not letting up. Day Five gives us a look at packed theatres, a view through 3D glasses, and an invisible Sean Penn?

Don't forget to use #sundance when posting to Instagram so your photo has a chance of making our daily roundup. And also follow us on Instagram at username sundanceinstitute.
