Any treadmill exercisers willing to share

I prefer the great outdoors, but I often have to run on the treadmill - not by choice. I fight the boredom by varying inclinations and speed just to play mental games with myself. ("in two minutes, I will reduce my speed by 0.5" "four more minutes 'til walking break", etc.). I also devised a contraption to attach my ipad to the board and I pick a movie / you tube video that is just about the right time the time I want to run.
