Today I see another prototyping tool. I really don't care about the specific tool o how cool is the application (in fact is pretty similar as Quartz Composer), but the good part is seeing new things like this in the App industry. I always say that the game industry is far ahead from us. You just have to see the Unreal Engine visual language and how powerful that is. Good programmers will always be necessary (I hope) but making tools to make our job easy is important. Not only to allow develop to non developers (I really don't believe in that), but for make our own job easier. The future will be amazing.
