As it states on Kickstarter, "All circuitry is wired, adhering to the highest electric standards. Upon placing the acrylic glass design in the lamp’s base (where the LED is positioned), the light breaks through the etched surface."
You can change out the designs simply by lifting out the acrylic from the base and snapping in a new one. Watch the video, below, to see what we mean. (They had me at the "balloon" design.)
