+cyberay
+=======
+Cyberay is an experimental renderer, and eventually game, aiming to explore the
+viability of realtime raytracing on high thread count multi-core CPUs. The plan
+is to utilize the GPU only for UI drawing and post-processing, possibly
+denoising, while leaving all the game rendering to the CPU(s).
+
+The project name is derived from the planned cyberpunk aesthetic of the eventual
+game, chosen to maximise interesting light sources and shiny environments which
+should suit the renderer well.
+
+This project is in a very early stage.
