Albert Kalchmair is an independent Austrian developer who publishes lightweight, keyboard-centric utilities under the GitHub handle “houmain.” His catalog centers on tools that streamline graphical asset pipelines and input customization for power users, pixel artists, and interface tinkerers. The first utility, keymapper, is a context-aware remapping engine that rewrites keystrokes and mouse events across Windows, Linux, and macOS; it lets gamers assign layer-sensitive shortcuts, enables left-handed users to mirror entire layouts, and gives coders vim-style navigation inside any IDE without admin rights. The second utility, spright, targets 2-D artists and indie studios by automating sprite-sheet generation: it packs ragged animation frames into power-of-two atlases, trims transparent borders, writes JSON or XML metadata for Unity and Godot, and can annotate hit-boxes or pivot points from command-line scripts, making nightly asset builds trivial. Together the programs exemplify a philosophy of unobtrusive, file-driven workflows—no splash screens, no background services, just portable executables that slot into Make, CMake, or CI pipelines. Albert Kalchmair’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the newest upstream release, and can be queued for batch installation alongside other applications.
