Lightning Image Viewer – overlay, map-like controls, toggling, image-rs
Hi HN! I'd like to share my app for viewing images the way I find comfortable on a desktop computer. No window frame, no menus, no toolbars, just the image itself in transparent fullscreen overlay; pan (move around) with mouse with left button pressed (or keyboard arrows), zoom into point under cursor with scroll (or into point at center of display with keyboard +=/-/0), close with left click anywhere (or keyboard Enter, allowing "instant toggle" between file manager and image view). Written in C and Rust with SDL3 and image-rs. Source and builds for Linux (Ubuntu 25.10, Nix expr)…

I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
