What is the gray image with two waves?
What is the gray image with two waves?
The primary image we have been using on our Ping Practice website (and as our prototype iOS app icon) depicts two subtle concentric ripples in a gray puddle that overlap slightly.
We enjoy how it visually represents the practice of listening to pings and beginning to notice their overlaps in “Ping Practice.”

This image is a still from IBM’s A Boy and His Atom: The World’s Smallest Movie. The film is viewable on YouTube and our still exists at the 37 second mark. Thanks to Perry for helping us track its origin!
Finding this elemental physics reference has been grounding for us, as we’ve been considering “ping” as our “core atomic unit.”
By the way, it’s May 2025, and we are wondering:
Are you pinging??
Feel free to share your “P.O.T.M.” (ping of the month) and why it’s meaningful to you.
