This heady piece of glass work is on display and is for sale at Denvers infamous Glass Store ILLUZION Glass Galleries ( its more of a  glass museum in my mind)

"The Throne" is considered to be one of the most iconic and legendary functional glass pieces in the industry. Standing nearly two feet tall, this mega collaboration was constructed in 2010. The skulls, made by Scott Deppe, remove from the top revealing the mouthpice, and the structure itself was assembled by Darby Holm using the Deppe's Darkness color. Banjo constructed the one foot tall goddess that sits upon Darby's lattice of bones. The airflow of this piece begins at the push bowl, where it travels down into a large natural percolator and then on up the skeletal backbone to the mouthpiece. Since this piece was first exhibited, there have been several similar pieces created, but this one will always be considered the true original.
