Well what do you know, the lamp we’re talking about right now does something very similar! Instead of the lamp moving, this, the “Etirement” lamp, has easily adjustable intensities of light.

Based on an orgaic skin-and-bones body, the Etirement has both: a skin and a skeleton. Pulling the rod you see in the center there adjusts the light the lamp gives off. The intensity of the light lowers down and rises up according to the distortion of the fabric membrane.
