The special effects crew behind the new Biblical epic Noah used a custom iPad app to control a huge overhead artificial rain and lighting rig that was capable of pouring 5,000 gallons per minute of water and turning night into day. WIRED went behind the scenes to see how the FX team put it all together. And on the eighth day, we got apps. Director Darren Aronofsky’s new film Noah is, of course, about the Biblical flood so massive it required one man to build an ark. Bringing such an apocalyptic deluge to the big screen was no easy task, and it required the special effects team behind the movie to, well, make it rain.
