Moving your company into a shiny new office can lead to numerous favorable results: happier employees, increased productivity, and even artsy photoshoots, to name a few. The large, collaborative chalkboards in the new office of Basecamp developer 37signals happened to inspire the company to build Chalk, a free Web app that lets you draw on your iPad using the Safari app—even when you're offline.
Chalk was put together by a couple of 37signals employees during their spare time. Since it's a Website and not an actual app, Chalk was spared the App Store approval process, and since it's programmed using technologies 37signals employees were already familiar with, the app took only a few days to write.
To use Chalk, simply visit the Chalk Website on your iPad and you’re good to go. Chalk’s interface is minimal and straight-forward: select either a white or red chalk to draw on the board, and select the eraser tool to erase. Using the tap-and-hold gesture, you can save your drawing to your iPad’s Photos app; from there, you can attach the saved drawing to an e-mail or sync it to your Mac. If you bookmark Chalk or add it to your iPad’s home screen, you can even use the Web app when you’re offline.
