Vale, LOGO creator Seymour Papert, who taught us that code can be creative play

Arduino-fiddling kids, and the rest of us, owe Papert a debt of gratitude

Back when dinosaurs ruled the Earth and I was a kid, I received the gift of a "100-in-1 Electronics Kit" that taught me the basics of electrical circuit design as I strung pre-cut wires between springy posts. At the very centre of this kit - its beating heart - a single transistor could be wired to work in an amplifier, or AM radio, or tone generator."
