The Mach series is inspired by aviation. I've always been fascinated by flight and space exploration, and wanted to have something that matched that for mechanical keyboards. As the first sculpt brought to life, it has a special meaning to me, and I hope it does for you too.
The challenge was getting the design to look good lit and unlit. A ton of research and experimentation went into it, and the end result is a keycap that can pick up any color. In backlighting that transitions, it also makes a corona effect.
