The Moebius strip helped me make a connection to the way some rational graphs behave near their asymptotes. Take the function 1/x ...to the right of the yaxis it's reaching up into positive infinity and to the left of the yaxis it is plummeting into negative infinity. The asymptote is rather like the line one draws down the middle of the moebius strip with the twist happening out there in infinity. I might be all wet but it works for me.
Also, I thought I read somewhere that some conveyor =type belts have a moebius twist in them so that the surface on both sides is worn down evenly. Does that make any sense or was I just taken in by one of those Paul Bunyan stories about the moebius strip? >
