I am looking for the name of a particular kind of animation software.* I have seen what it can do without knowing what tools created it.* I am confident the people here will know immediately what I am describing.* It has the appearance of someone drawing on a white board.* As the voice over is talking, it seems that someone is drawing with a dry erase pen on a white board rapidly and flawless to illustrate the voice over.* Can anyone here tell me what this thing is called?* Somehow I doubt the video animation was made from scratch.
