i remember playing tetris on our old (but at the time, super fancy) nintendo. we played so obsessively that my sister and cousin had nightmares of being chased by tetris blocks. i saw this tutorial over on craftster awhile ago and put it in my "to make pile". it kind of got lost in there until recently. they're so easy to make and it's a great project to work on while watching tv. i found it to be very soothing.
