"Professor Alexander's Botanical Vasculum - Steamed 300 watt Moss Terrarium from Etsy seller SteamedGlass is a beautiful blown-glass steampunk Rube Goldberg terrarium: "This is the largest of our "steamed" light bulb terrariums with a bulb measuring 3 3/4" x 7 3/4". It stands 10 1/4" tall as mounted on the SteamPunked stand made of a simulated cherrywood base, copper tubing, chemistry glass, an adjustable 4x magnifying glass and other ornate trimmings. The bulb houses a small solar powered LED bulb that lights itself when all other lights go out and throws a dreamlike shadow pattern on your walls making the perfect night light. It can also be turned on and off with the old fashioned knife switch mounted to the base."" - Steven Perez from Bookmarklet
