An artistic use for an energy-hogging lightbulb… Designer Steve Witteveen creates his nifty little terrariums inside upcycled incandescent lightbulbs. Witteveen carefully places mosses, wood and stones inside the bulb to create tiny green environments.

The 150 watt moss terrarium featured here will cost you $45 @ the SteamedGlass Etsy shop

The low maintenance terrarium comes pre-assembled.
