LumiSource is behind some of the coolest plasma lamps we have tested. Its anatomical human heart plasma lamp is also pretty rad. It reacts to your touch and doubles as a physics toy to light up Neon, Argon, and Krypton.
The LumiSource Sculptured Electra Heart Plasma Lamp measures 10″ tall with its base. It is rare but you can find it on sites like eBay and Etsy.
