I was "playing" with this great website called Flipbook on my tablet this weekend with my kids. It is a pretty cool animation website that allows you to draw frame by frame images of an animation complete with onionskinning of your previous image. So you can choose to draw over it or make slight changes.
Me and my kids had a ball drawing up several things and they are going be using some of the anime in their music video they are doing for a summer project. It is great to see your kids excited about using technology.
If you have a few free minutes be sure to check it out!!!
