Depending on who you talk to, this sculpture can or can't be used as a hookah. What is more certain is that it was made by glass artist Kevin Murray of Milwaukie, Oregon.
Definitely can smoke with it. Here in Oregon, especially around the Portland metro area there are tons of amazing glass blowers who create beautiful "funtional glass art." No glass blower in Oregon would create such a masterpiece if it was not "funtional." Guaranteed.
Seen a few pictures of this one. It's a waterpipe that is listed for $10,000-20,000 with around 200 man-hours or something of the sort.
Antenna is the bowl/carb and you have to put it on to use it because the mouthpiece on the inside :-D
