Kanesta

Has anyone ever played this game name kanesta?

I was sitting in the library browsing thru the different forums when this lady came and told me that I was just abt to use that computer( the one I was using). I was like excuse me. She said she uses this computer to play a game call Kanesta. Its a car game and she found it very relaxing and she particularly uses the same I was using right now because the other one's dont have good connection and she cutts off in the middle. She further told me that she told about this game to one of the librarians here ( the bulky girl who is at the desk in the morning)and now she also found it so relaxing that she told her that last night she played that game till 3 am. Since I wasn't in a mood of conversation and she seems to convince me about the game I offered her my seat and now I am sitting at the other computer just in front of her. And she seems to be fully absorbed in that game.
So I was wndering has anyone ever played this game? How relaxing or in other words addicting it is?
