Our younger child, David, has a birthday today. I wanted to celebrate by making a card that says something about who he has become in these last 38 years. The enormity of summarizing a complex and wonderful human on a single card nearly did me in. Eventually, though, I got to thinking about how his work brings him such pleasure and how accomplished he is. So I drew him at the computer and overlaid the screen with code and images that I hope convey blockchains. The next part, giving David’s face the expression it gets when an idea charms him, was harder, but eventually, I got one that I thought was true to him. Finally, I made a background with a hint of a graph since graphing goes with data crunching. Then I had the fun of including his age and a toss of confetti, in a nod to those childhood birthday cards.
Happy Birthday Dear David!
