Trinagon 3D Intuitive Logic comes from Lucas Pradlwarter. The object is to swivel/rotate circles of triangles to create specific patterns.
Mad Triad from 2010. This is a mechanical puzzle that operates on the same principle. The concept was first developed by Doug Engel in the 80s.
Trinagon Sample which was only 2D.
I have not played this game a lot. (I've slowed my puzzle playing a lot as you may have noticed.)
Lucas: great job!
