David Em is an American digital artist who made his first digital image at Xerox PARC in 1975 and built navigable 3D worlds as artist in residence at NASA's Jet Propulsion Laboratory.

David Em provided covers for a few Herbie Hancock albums, including Future Shock (1983) which I just received in the mail recently.

I can still remember the first time I started sending pictures to magazines and things by sending JPEGs over the web.
