Other projects are more clever than pragmatic, but they could still have their uses. The Voice of Netflix uses a neural network to grab dialogue from streaming shows and turn them into new sentences on demand. If you want to hear characters from The Crown recite something silly, you can. TerraVision helps show producers find locations by matching one of their photos to a library of location shots. And no, Get Out! isn't a Jordan Peele nod -- it's a tool that plays awards show walk-off music in any Netflix meeting room to let people know when they've overstayed their welcome.

As with other Hack Days, we wouldn't expect most if any of these efforts to become part of Netflix's service. Project Rumble Pak does show that the company is interested in experiences beyond sight and sound, though, and we could see it happening if Netflix wants to drive more viewers to its mobile apps.
