The original app (Action Movie FX) is done by JJ Abrams' Bad Robot Interactive. (For those who don't know, Abrams did "Lost," "Mission Impossible: Ghost Protocol," "Star Trek," and "Felicity.") A couple of friends of mine have it on their iPhones, and they love playing with it. I'm going to download the Ultimate Movie FX for my Cappy and see how well it works.
UPDATE: It's not listed in the mobile version of Google Play, and the developer's website has broken Javascript links, so it's not apparent whether they actually still support it or not (even though the Web Google Play site shows it was last updated in April of this year). Can't do it from where I am now, so I guess I'll have to do it from home later.
