Well now this is quite unexpected - Microsoft is making some big changes to Paint.
You all know it, the simple drawing program which comes with any install of Microsoft Windows which has been used to distract toddlers for generations. Now it's getting a new version which includes all of those elements you've come to know well plus some fancy new additions like the ability to create 3D art.
Here's a quick preview.
It looks good, and has been very much designed with touchscreens and the Surface Pen in mind. Right now there's an early version of the app which you can test- with full installation instructions over here. We might wait for a full release, which could take until 2017 to arrive.
