new wheels for the fastback

it's the same concept with airplane propellers. somehow the rotation makes it look like it's changing direction.

Trying to not sound like some kind of "techno-geek-oid":... the tire illusion has to do with the tire's RPM versus the "frame rate" of the movie camera. It helps if you've ever seen some old movie film - it's just a series of "slides" or pictures, just on one continuous piece of film. The frame rate is the number of "pictures" (frames) the camera takes every second as it records a movie; known as "frames per second" or FPS . Same thing happens with digital video cams. If the RPM's of the tire are more than the FPS-times-60 (60 seconds in a minute); the wheels appear to moving forward; if the wheel RPMs drop below the "FPS times 60" number, it looks like the wheels are backing up....

Now that I've already managed to make myself sound like a geek anyway; I just gotta say, "Great vid!". The more I look at the video, the more I like the shiny Bullit's. And the car sounds great! Between the screamin tire and the lumpy-sounding cam; you're gonna scare off most of the wannabe's :D
