• Point-cloud clockOct 14, 2026 — Six balls of points that show the current time HH:MM:SS; each ball turns to show its digit, and you can drag a ball to spin it.
• A–Z point-cloud sphereOct 13, 2026 — A cloud of white points inside a ball that spells every letter A to Z when viewed from different directions.
• The longest thick curve on a sphereOct 4, 2026 — Put a rope of prescribed thickness on the unit sphere. How long can it be without overlapping itself?
• Shortest flight around a spherical planetOct 2, 2026 — Shortest flight around a unit spherical planet from which every surface point becomes visible. Numerical candidate, generated with Grok 4.7 in Cursor.
• Navier–Stokes equation (2D incompressible)Sep 5, 2026 — Solved live numerically on a discrete grid:

  ρ(∂u/∂t + u·∇u) = −∇p + μΔu + f, ∇·u = 0.

  The ink (the white stuff on the left) is added so you can see the motion of the fluid.
• PercolationSep 2, 2026 — Each edge (in a square, triangular, honeycomb, etc. lattice) is kept with probability p and removed with probability 1−p. See what happens at the critical probability p_c.
