Every year, on the last week-end of July, my hubby and I wandered through the local Arts fair knowing that we rarely can afford the beautiful and creative artifacts on display. Last year at the Blink in Time booth, we had the pleasure of experiencing David Roseburg’s handmade clocks. They are so fun and diverse, but he really knows what tickles the math teacher’s heart: prime numbers, the digits of pi, the Fibonacci sequence. After a year of regret, I splurged on his Fibonacci Spiral clock, part of his “Geek” designs. I’m smugly proud! What kind of mathy clock would you want for your desk?
