A fun game designed to train and strengthen your dynamic (kinetic) vision. Invaders will appear on the screen coming towards you and getting larger. Click on them to make them disappear...but they keep coming, level after level! See how far you can get! To get the code, go to the widget's webpage and scroll down. Step one asks you to select a color, click on your favorite color. Then copy the code in Step 2. That simple. Put that code wherever you want on your blog or website.
