How Sony put 40,000 PlayStation symbols under your fingertips
I’m not sure you understand how many PlayStation symbols Sony snuck in.

Part of that is how the amazing DualSense controller’s clever motorized triggers and intensely precise vibrations can recreate the crunching sensation of strutting across a sandy beach or the pitter-patter of rain.
Another part: the 40,000 tiny PlayStation symbols you’ll feel when you pick up the PS5’s new gamepad. As an Easter egg for its fans, the company decided to apply a microtexture to the DualSense controller’s entire lower shell that makes it Sony’s most grippable gamepad yet because of the thousands upon thousands of tiny squares, triangles, circles, and crosses literally at your fingertips.
Sony hasn’t previously spoken about how it did this, how many there are, or how large the symbols actually get, but we have those answers today — including behind-the-scenes photos and details from Sony’s Yujin Morisawa and Takeshi Igarashi, the chief designers behind the PS5 and the DualSense, respectively. (We even borrowed a fancy industrial microscope so you can see how the symbols look up close.)
Perhaps the most striking part, as you’ll see in images above and below: these tiny symbols are stacked on top of each other, jutting out in three dimensions. They’re not a single, evenly spaced layer at all, like the tiny dots you might remember on Sony’s DualShock 4 from 2013. They look random, almost organic — which might be because the entire design was sketched out by hand.
