You heard #Adobe. Deep down you knew this was coming. Now all your art are belong to them. Time to move on to better things…
Kreative Suite
* Krita is your new design/painting app
* Kdenlive will give you video-editing powers
* glaxnimate adds 2D vector animations to you videos
* digiKam organises your collection images

Also:
* Inkscape - create sophisticated vector-graphic designs
* Scribus - layout like a pro
* GIMP - need we say more
* Blender - ditto
Gimp might be allright but I prefer pixlr (an online app) as an alternative to photoshop.
