Drawcast is a really simple application that allows you to draw on your tablet or mobile device and display it on your TV with Chromecast. Pretty cool for a toddler to play with or if you want to leave a message for a loved one I’ve got a feeling this is only the start to what we’re going to see out of Chromecast, for example interactive games for kids on the tablet or mobile device that can be displayed for all to see on the big screen.
