Posterize  

I wrote a simple Android application, that uses the Android Renderscript APIs to create a neat image filter. This filter makes the output image look like a poster color drawn version of the input. So create your masterpiece and share away.

The app is on the Google Play Store. Looking forward to the reviews, if you have any suggestions for improvement.

Here is an example output image; The Bay Bridge at the Embarcadero in San Francisco.
