Just went to download Sketchbook and noticed it's been made free to use!
"At Autodesk, we believe creativity starts with an idea. From quick conceptual sketches to fully finished artwork, sketching is at the heart of the creative process. You never know when a great idea will strike, so access to fast and powerful creative sketching tools is an invaluable part of any creative process.
For this reason, we are excited to announce that the fully featured version of SketchBook is now FREE for everyone!"
Happy days! Hope this proves useful to someone! Spread the news, you never know who might be inspired to start arting!
Cheers,
Rori
