Krita is a painting program for digital artists. It is not just fun to paint with, but it has also very nice and funny community.

Record Krita in action. Compile Krita 2.3 trunk and record some cool new 2.3 features in action like brush engines, mirroring and rotation of the canvas. Full list of new features can be found here http://wiki.koffice.org/index.php?title=Schedules/KOffice/2.3/Feature_Plan#Krita

Outcome: Happy developers, better visibility of Krita in the digital world
