Sure we all want our own private island, but Neatorama's favorite performance artist Antti Laitinen actually did something about it: back in 2008, he built himself a floating palm island that he rowed on the River Thames! The police, however, didn't seem to be too enthralled with the idea:
I rowed my palm island down the Thames with the aim of rowing through the centre of London. After a few kilometres of rowing the police pulled me over in front of MI5 and stopped my performance. They asked me if I knew what building I was beside and I said 'yes, that's along were I am going.' They didn't agree, and towed my island and me back up river.
