I’m too old to be nostalgic for skeuomorphism. But a retina-burning amber monochrome monitor, text mode, with menus and UIs built out of ASCII graphics, or at best, 640 x 480 CPU-driven graphics modes? Now you’re talking.
From my perspective, the skeuomorphic era of the early-late 2000s is still “modern”.
How do I type something? There’s a cursor but keyboard input doesn’t work for me. You oughtta make it do some dummy commands for fun, or better yet, some real ones in a sandbox, that’d be neat, for fun user interactivity. Otherwise, looks slick. Good job.
