This is how I would set up 1, 10, 100 and 1000 lightbulbs in a cubic space:


These arrangements follow the extension from a point in space, to a line, to a plane and finally to a volume.

My arrangements are also organized in a grid system, whereby the lightbulbs are regularly spaced from one another and reflects the planes of the interior space itself. In the 100 and 1000 examples, I also find that there is a spatial tension within the arrangements because the separated clusters of lightbulbs share strong similar visual traits to one another.

I think that the way I have arranged the lightbulbs also emphasize the centralized form, and hence presents very stable and dominating visual.
