Show HN: GPU‑Accelerated Desktop Screen Flash Filter for Photosensitive Epilepsy

A developer posted a Show HN entry introducing a screen flash filter designed to help users with photosensitive epilepsy. The filter runs on the GPU to process desktop visuals in real time. It aims to diminish rapid light changes that can provoke seizures. The tool is accessible via a web application at flashfilter.app. Users can enable the filter to smooth out flashing content across applications. The project demonstrates a practical use of GPU acceleration for accessibility. Feedback from the community is invited to improve effectiveness. Future updates may expand compatibility with additional operating systems.
