I have been inventing since 1967 when, sitting on my surfboard at Torrance beach in California, I invented flexible fins. I did not pursue that but later thought up a variety of new products.
The most satisfying was my webcam software I created in 1995. Carl Sutter helped put it into reality using Visual Basic software and in 1996 Sean Collins, the brilliant oceanographer who created Surfline.com, bought my software to help him stream the 1996 Surfing Open contest at Huntington Beach pier.
