Alma is a prize-winning (secular) animation by Rodrigo Blaas that is hugely compelling. And chilling. A visual metaphor of entrapment. A real discussion starter – it would be useful to show, for example, to a youth group. Or as a embedded clip within a website, asking questions.
There is so much to see and analyze within it, with spiritual parallels and warnings. You’ll need to watch it several times, in full screen. (That’s the second control from the right, in the toolbar under the video.) Link from Internet Evangelism Day.
