Triple QR

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 250.2 Hz, 77 cents flat of C4, the nearest tine on the comb. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Tap to pull the three codes apart. Read all three, or pick their colors, in the Splash tab.

One square holds three QR codes here: the first sets each module's red, the second its green and the third its blue. So each module is one of eight colors, from white to black.

Splashery's reader splits the picture into its red, green and blue and reads each one as an ordinary code, for three times the data in the same square. An ordinary phone reader sees only gray, which comes mostly from green, so it usually reads the green code or nothing. Tap the square to pull its three codes apart and back. Type your own three texts in the Splash tab, and pick the color each code shows in when pulled apart.
