From the designer's son, about the game Watch Your Garden Grow
"My father, Robert W. Bingham, invented and made this game in 1966 - 68 (?) We manufactured it at his office in downtown St. Louis. The space "capsules" were little plastic airline salt and pepper shakers that we spray painted by setting them on rows of tooth picks on one of the styrofoam boards that made the base of the game. (A a later point we framed it and hung the board up as abstract art in our house ala Jackson Pollack.) The mechanism underneath was a saw blade shaped 1/8th inch cardboard wheel, with day-glow red and green squares that could be seen as red or green circles on the top of the board. If you landed on a red spot, you had to skip a turn or you couldn't go until it changed to green, or something.
I think what sunk the game was the expense of doing it right. I remember my father talking about the cost of the die to either cut something or set up the injection mold it costing $100,000 in 1960s dollars. I expect he sold a few hundred of these games, certainly no more than a few thousands. I have a picture of him selling them at Sears. If I remember correctly, Sears was already to go, but he needed to be able to supply them and make it cheaper. I was six when he started making the game, but he talked about the process all through my growing up."
