Craftster Kris DeGraeve for put up a 16-step guide for creating your own Space Invaders lamp (or chandelier) with glow in the dark aliens, like the piece above. The light source runs on a 9-volt battery, and required a bit of "3D modeling/printing, laser cut acrylic, resin casting, UV reactive pigment, LEDs" and simple wiring to bring it all together.

It sounds like the type of afternoon project that somehow morphs into an entire-weekend affair! Once you've got it working, though, you can slowly sway the lamp side to side, pretending the aliens are approaching the surface of your soon-to-be subjugated end table. Here are some larger shots of DeGraeve's lamp:
