ColorMeBad 畫我壞壞

ColorMeBad is a fun app that lets you take a picture of anything, draw on it in different colors, and share the result by messaging or email or whatever.
Shake your phone to erase your drawing and start again.

This app was developed on MIT App Inventor http://appinventor.mit.edu/ and is a simple variation of the Digital Doodle tutorial app. App Inventor lets anyone build an Android app using only a web browser and a phone.
