mausimus

mausimus is an independent software publisher distributing open-source projects through its GitHub repository, with a focus on graphics tooling for the Windows platform. Its catalog centers on ShaderGlass, an overlay application that applies GPU shaders on top of the Windows desktop, as well as applications running under Wine on Linux. ShaderGlass captures the screen or a selected window and renders it through shader effects in real time, allowing users to modify the appearance of any visible content without altering the underlying application. A typical use case is retro gaming emulation, where the overlay can reproduce the look of classic CRT displays—including scanlines, curvature, phosphor masks, and color bleed—over modern emulators, PC games, or even entire desktop sessions. Beyond gaming, the software serves users interested in visual post-processing, such as adding filters to media playback or softening the output of legacy applications. Because it operates as a transparent overlay rather than a plugin, ShaderGlass works with software that has no native shader support, making it broadly applicable across both modern and older programs. The project fits within the desktop utilities and graphics enhancement category, sitting alongside tools for screen capture, display customization, and emulation front-ends. It is built around widely used shader presets and supports customizable parameters, giving users control over scaling, input sources, and effect intensity. Distributed freely through GitHub, ShaderGlass reflects the publisher's emphasis on practical, community-oriented utilities that extend the visual capabilities of the operating system, appealing to enthusiasts of retro computing, streamers seeking distinctive visual presentation, and anyone looking to apply GPU-accelerated effects to their everyday desktop environment.
