Less known design software

We all know Adobe CC and Cinema but here are some lesser known but useful pieces of software.

Mischief Paint - Love this software. It behaves like a raster based paint software but has infinite resolution like vector based software.

XNview - Nice image browsing software that supports 500 different formats

Krita Paint - An increasingly interesting paint program.

Sculptris - Super simple 3D sculpting software

Wings 3D - A very simple modeling program. A nice program to learn some modeling fundamentals if you don't want to spend any money and Blenders UI is too crazy.
