I only just found out about Clint's passing, and I'm so sorry to read it. I would see Clint at professional conferences about once a year, and he was always so passionate about sharing his work and why it was so helpful to designers and creatives around the world. I would search him out on the exhibit floor because talking to him was like drinking a cup of coffee—his energy was infectious. I miss that.
He came to speak at a conference I produce in 2019, and people said "what I learned in that one 20-minute session was worth the cost of the whole event." He was great.
My condolences to his whole family. May his name be a blessing.
