One of the things I like the most is creating art, the number of dimensions don't matter.
Mostly, I model 3D characters in Blender or use Krita to draw (in 2D).
Both are free (as in software and in beer) and really great to use!
There are also some other things that run on this server, such as a [matrix] server (like email, but for instant messaging and 10x cooler) and nextcloud. Feel free to contact me for a free account!
