A bit of a confusing #audiomo this evening as I’m so so tired from several days of working in my basement. But here it is, in which I discuss not one, but two softwares with very similar names, but completely different functionality.
You can download Pencil2D for doing flip-book type animations at http://www.pencil2d.org
The GUI prototyping Pencil is available at https://pencil.evolus.vn/
Both are available for Windows, Mac and Linux
