There are over 2.7 trillion known digits of Pi. This irrational (non-repeating) number we all remember from primary school has inspired all manner of artistic endeavors, from Kate Bush’s song “Pi” to Martin Krzywinski’s data artworks. Now, for Pi Day (March 14), music software programmer Canton Becker has crafted a million-hour song based on Pi that unfolds generatively on a virtual tape deck.
Titled “Shepard’s Pi,” the song combines two of Becker’s favorite infinities: Pi, and an auditory illusion called a Shepard tone, which he describes as an “unsettling sonic illusion of a pitch that climbs or descends forever, never reaching a top or a bottom.”

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
