I used to drive a 1980 Pinto. It was the last year it was built, the exploding gas tank issue was long fixed, so no jokes. Actually it was great car. I loved it and drove it over 12 years. It was a little beefier looking than the original Pinto, it looked like it had been spending some time at the gym.
Anyhow... One time I saw another '80 Pinto at a stop light, you know how when you drive one make of car you notice every other one on the road. This one had a completely different look, very sporty and lithe. I looked harder and noticed that it had a non-linear pinstripe going down it's side a few inches from the hoodline all the way to the back. A little above the rear wheel/quarter panel area, it had a rise to it. That little rise created a visual change in the visual lines of the car and gave it a very different visual effect, that really changed the look of the car (from the side at least). It went from a chubby look to lithe and sporting in almost a British way. Amazing.
I've often thought about how that
one pinstripe deeply changed the visual lines of that car.
When I removed the side chrome from my bike, I noticed how the fender shape along the bottom contour, was quite stodgy. Where the rest of the fender has curvy lines that play off each other, the bottom edge hangs low and leaves a big flat ungainly panel on the side.
I wondered how a well placed pinstripe would change the visual contour.
Whe I saw Greg's picture, I thought, "There's that flat panel again." So, I lifted a copy on his picture and fiddled with it in plain old PBrush. Notice how the stripe rises directly above the forward downward curve.
I think the stripe I did draws the eye away from noticing the expanse of flat metal and into the line of the pinstripe, which, IMHO looks much more balanced.

Whatdya think?
