"Adjusting animation speed" by @HalbFettKaese fragcoord.xyz/t/ak2povht This is a great interactive guide on how to handle changing speeds with linear time in shaders. I was actually about to write something like this!

Excellent visualization! This is basis of the technique I called "turbulence" which I use in my tiny shaders for fluids, smoke and fire. It's cheap and deterministic

Less than 4 weeks left to write the best article for FragCoord. It could be a tutorial, breakdown, devlog, showcase anything graphics related. I'll be giving the best ones a FragCoord Pro for a year (which unlocks 3D buffers, compute shaders, MRT and more)

Which direction should FragCoord take? 1. More audio/music tools 2. Visual Programming 3. Optimization Tools 4. Something else?
