Fractal Twin-Bulb Lampsean michael ragan posts this ingenious algorithm: combine twin-bulb adapters into neuron-like structures:

The first manifestation of this idea was as a table lamp, incorporating only 15 adapters and using pink bulbs and a commercially-bought lamp base. The fractal arrangement of the adapters in space suggested nerves innervating tissue to me, and so I chose the pink color to suggest (hopefully) a brain. The lamp was called “Brainiac” and was dated 9-18-2001. It was, in fact, quite ugly, and the light it gave off was fit only for a whorehouse. It was eventually dismantled, and the adapters cannibalized to make the much-more-successful fractal chandelier.

Ingenious indeed — it lights my neurons, for sure!

He continues:

Nimbus LampThe chandelier is essentially a binary tree in 3-space. It is symmetrical, with each adapter, except the top one, being positioned at a 90-degree angle relative to the axis of its parent. After assembly, a drop of cyanoacrylate glue was applied to the junction of each pair of adapters to keep the structure from deforming if the chandelier is moved or jostled.
