well, this bubble city is obviously a bit far-fetched.. LOL... but they ARE in the works of creating an underwater hotel which i think is just awesome - to my knowledge, no one else in the world has thought of something like this??!

AND they just finished creating this massive "palm island" with hotels, apartments, houses, grocery stores, malls, etc... and it looks like a giant palm. basically so people will never have to leave the island (except for work, maybe!).

i was there last september and they really are trying to make this place "THE PLACE" to go for out-of-this-world stuff... it really is amazing there
