+# El-gpu and pix-el: GNU Emacs 2D and 3D game programming
+Emanuel Berg (he/him) - Pronunciation: Swenglish, IRC: lacni, incal@dataswamp.org

+
+In this project, prepared especially for EmacsConf 2026, two modules -
+`el-gpu` and `pix-el` - for graphics on-board the GPU and CPU,
+respectively - have joined forces and been adapted to the newly added
+canvas format, an exciting new feature included in vanilla GNU Emacs.
+
+In this video we show no less than three games - a snake clone, which
+operates on a per-pixel basis; a Tetris game, with tiles loaded on the
+fly from any visual creation even as it only exists in drawing
+program, still a dynamic, editable object; and a Descent-like space
+shooter, powered-up by SDL and OpenGL, executing part CPU-side Emacs
+Lisp (Elisp), part CPU-side dynamic module C, and part all-GPU GLSL.
+
+el-gpu and pix-el, like their predecessor, bad.el (boxing after dark),
+which was demonstrated at EmacsConf 2025, comes with an interactive
+studio, that has its own UI; it offers OOP-style drawing, as well as
+explicit pixel-plotting, with layerjs, procedural shaders, functional
+alpha masks, and RGB bitwise blenders, including for transparency;
+with image editing, effects, rotation, and transformation, with new
+idiomatic GNU Emacs lisp, e.g. the `with-pixels` macro; also offering
+several ways of drawing text on the CPU as well as GPU; and much more.
