The same website makes metal buttons, resin buttons with real bugs inside, and more. Overall it’s not really anything I’m personally interested, but I love that the deck has enough support, and is tinker friendly enough, that stuff like this is even an option.
I really wonder how they’d consistently source that, but mostly I just hope I never ever hear about it again.
I mean, custom steam deck resin buttons containing insects is probably niche enough not to have to source many of them.
