How to move multiple objects in relation to central point What I mean precisely is how to move multiple objects away from central point without scaling them. 

This is what I'm working with:


I'm searching for a way to create little space between the triangles. All triangles are separate objects.

Or if you can do this with scaling that's ok too ofcourse.
In the header of the 3D window change the pivot point from median point (default) to "individual origins", then select all objects and scale.
