Creating an Array of Objects With Self-Emitting Materials

Today, I’ve been learning how to apply a self-emitting material to an object and create an array of those objects. The initial plan was to use Geometry Nodes in Blender to create the array, but it turned out too complicated. Using Python to duplicate the base object 6 x 6 times and offset them in a grid was much easier.

I need to learn Geometry nodes, nevertheless, but in time.

In a very general level, here are the steps:

1. The base object was copied with Python and the copies were placed in a grid.
2. The object's color was modified so that it emits light and doesn't need a light.
3. The camera was aligned to show the grid with the key combination (I keep forgetting this): Press 7 (numpad) + Ctrl + Alt + 0 to align the camera to the current view.

Here's how it looks:
