Magic Pen

I discovered this while exploring another site. It's called the Magic Pen. It is similar to the Line Rider game. The object here is to get the red ball to hit the flag(s). You do this by drawing shapes such as circles, triangles, etc. You can even connect objects using pins and hinges. This has a lot of math and physics concepts and it's fun. The game continues for several levels with each level more difficult than the previous.
