Code and circuitry find their way into the mouse’s design
The limited edition is presented as a mouse for developers who write code every day and build the digital world.
The matte shell features symbols such as “//” and “</>,” circuit-inspired lines, and graphics incorporating “Hello, World.”
It also incorporates numbers and symbols associated with programmers and open source.
It’s nice when an everyday tool features design details connected to your work or hobbies.
It’s the kind of design that makes you imagine how it would look alongside the keyboard on your desk.
