I just bought these (the black ones) to cure boredom and relieve stress, but I'm not sure that was such a good idea b/c I have a bit of A.D.D.
I'm never going to get anything done now b/c I'll be messing with these things. They are cool. I'll have to get a lot done before they arrive in the mail. lol
