how to make a line rider movie?

Answer 1

Use this software, and just draw lines and hit play. You should be able to save it as well: http://www.download3k.com/Games/Simulations/Download-Line-Rider.html

If it doesn't allow you to save (I can't remember if it does) use a screen recorder while you are playing it like this one: http://camstudio.org/ .
