Halving the step should cut the error by 2 (Euler), 4 (RK2) or 16 (RK4). The final column is measured against RK4 at 16× the step count.

Add a million numbers the naive way and against Kahan compensation, and watch the error grow or stay flat.

Distances and coordination sequences on a lattice grid, for crystal and network geometry.

The logistic map from r 2.7 to 4.0, with the bifurcation diagram drawn live as you drag the growth rate.

Factor any integer, build a smallest-prime-factor sieve, and see the primes light up in a density grid.

Set direction, wrap, justify and align on a live row or column and copy the resulting flex CSS.

Draw a grid from a text sketch where every row has the same cell count and named areas form rectangles, then copy the CSS.

Set the four corner radii and the shorthand, and see the rounded box redraw as you type.

Tune blur, opacity, saturation and border tint on a translucent panel and watch the edge quality change over the backdrop.
