Looks actively developed, although it seems silly to *me* to work on this while Krita has faculties for "natural" painting. But it's their vision, and I hope that this shapes up to be something great.
It keeps on crashing 1-2 minutes after I open it. EDIT: More precisely, on my Windows 7 Home Edition 32-bit it crashes when I attempt to apply the third stroke (of any brush) upon the canvas.
