Cornell Clark Hall Car Cam and from Internet Archive Wayback Machine.

Internet Archive (Wayback Machine) has many uses: http://www.archive.org/index.php

Was trying to find my old webpages at the Cornell Materials Science Center (roughly 1995 onwards)http://web.archive.org/web/*/http://msc.cornell.edu/~putnam
http://www.ccmr.cornell.edu/~putnam/clcarcam.html
Had to navigate through link changes. http://web.archive.org/web/19990417232519/http://www.msc.cornell.edu/~putnam/clcarcam.html
So here is the record of my build archived in 1999. The actual Cornell Clark Hall Car Cam construction was in 1996. Wireless camera mounted on an RC car transmitting (on weak UHF) to a battery operated TV. But cannot claim to be first... it was based on an a segment on Letterman in 1994/1995.

There was one in toy stores in 2008.

Make Magazine 20 page 120 has a similar thing, but for a recording camera. http://makezine.com/20/

ala George C Hale, Hale Tours - where cameras were mounted on trains, footage taken and shown in cinemas.
