Im a teacher in second grade (7-8 year old kids, in french, sorry for the bad english) and Ive been doing projects with Green Screen Movie FX for three years. Its great, its easy. The reaction on the kids faces are fantastic and the comments from the parents are awesomes. You can import your own image. My students make their own drawings and I put it behind them on the screen. Its super!
