Here's a game - Can You Guess the Function? hint - it's way shorter than you're probably thinking

Not at all impossible, but super easy in fact, just draw it in 3D in @QuillSmoothstep

I talked to @wookash_podcast about some low level programing, C++, graphics, 3D, shadertoy, VR and many other (sometimes rabdom) things: piped.video/F1ax1iJTHFs?feature…

Yes, just replace x² with |x|: graphtoy.com/?f1(x,t)=acos(a…
