If you look at the vote count, you will see all most every pic has 1 vote for it so far.... You're clearly not the only one who voted for their own photo. ;D
I saw one of these aquascapes in person this weekend, looked really really good. Problem is my wife fell in love with it and is convinced we (meaning me) need to rip apart our rockwork and redo it. For that reason you lose my vote, you know who you are!
