Chalk: A Free Browser-Based App for Your iPad

The clever team at 37Signals came up with a cool, free browser-based productivity and art app called Chalk. Rather than messing with the App store, you can just go to the webpage, draw stuff on a virtual chalkboard, pass it around, do what you will, then save it into your photos library.

It even works without internet access. Check out the video below to learn more.
