What’s new (from this millennium, anyway):
Started jokey dashboard page.
Started Hilbert 4-D curves page.
Many more interpretations of Fuss–Catalan numbers.
Also variants of fractal sponges.
Added Fuss–Catalan numbers page.
Belatedly added Cantor set to Cantor dust page.
Added Hironaka’s curve.
Added One-sided toroidal polyhedra.
Added Padovan and Fibonacci spirals page.
Added Pancake-cutting problem page.
Added Koch surfaces page.
Added Menger sponge inverses to Menger sponge page.
Also belatedly added Greek cross fractal page.
Added 3-D versions to Schoenberg curve page.
Added symmetric unlabeled stamp foldings page.
Added symmetric stamp foldings page.
Removed links to SVG files, since my hosting service shows a horrible parked page for them. Let me know if you care, I guess.
First sketches of cross Menger sponge slices.
First sketches of Menger sponge slices.
Added figures of inverses of some cross-Menger fractals.
Added made-up houndstooth fractal to the Cross Menger (Jerusalem) Cube page.
Hasty notes added to the map-folding page.
Sketchy notes about two ideas related to the Jerusalem cube fractal, plus recent typo fixes.
Notes and pictures about continued fractions.
Added notes on cyclic permutations, also known as necklaces, bracelets,
stellated p-gons, and probably a bunch of other names.
Added Hasse diagram of Ferrers boards.
Added page on non-crossing partitions, yet another Catalan number interpretation.
Tiny changes to Self-avoiding loops page, such as letting anyone know that it exists.
Added Coin fountains page.
Added Unlabeled stamp foldings page.
Added Lah numbers page.
Added Counting Lattice Paths page.
Added Narayana numbers page.
Ditto, permutations page.
Added partition refinement lattice to the Bell numbers page.
Spruced up the Stirling numbers of the second kind page, not that you’d notice.
Added Self-avoiding loops.
Added Schoenberg plane-filling curve.
Bringing some math figures back home, with thanks to
The Math Forum for hosting older versions for
all these years. Fixed some errors, introduced others.
Updated long-unawaited self-avoiding path figures.
Added giant redundant figures for 4×2 and 5×2 labeled map foldings.
Linked to Mathematica Demonstrations for labeled stamp foldings and labeled map foldings. Fixed some obvious errors, which is depressing since it proves that nobody reads these.
More of the same: added labels to labeled map foldings.
More of the same: figures showing labeled map foldings.
Figures showing labeled stamp foldings.
Placeholder recursive images.
Drawing ovals using a pencil, three nails, and some string.
Fractal Wunderlich curves in 2D and 3D.
World premiere of fractal 3D Sierpinski arrowhead curve.
Fractal Sierpinski arrowhead curve and friends in 2D.
Hilbert and Moore curves in 2D and 3D. Deleted quaint page-size notations (75K, 15K, and all that).
Lebesgue curves (and friends),
Lebesgue curves in 3D.
Now this is just silly, but finally posted most likely final travelogue from 2006: A Room with a View of a Room.
Added Schröder numbers, other updates to Delannoy, Schröder, and Motzkin numbers. Oh, and happy new year.
Updated misc. MSI tips and notes. Oh, and happy new year.
New stairstep-tiling interpretation of Catalan numbers.
SVG versions of some Euler zigzag paths and Fibonacci tilings.
SVG versions of some Delannoy/Schröder paths.
Working on SVG versions of some math graphics (Catalan number and Motzkin number diagrams, for example).
Watch this space.
Disappointing new batch: When the Going Gets Tough, Tough,
Interchangeable, and In Other Words...
Disappointing reconstruction: Motor Skills.
Working on involuntary travelogues When the Going Gets Tough, Tough and In Other Words... Watch this space.
New facts and figures, words and numbers, dates and times, misc. cleanup.
Exeunt: Flavor of the Decade.
Almost there: The Next Big Nothing.
Double revision: Untrainable (Dec. 2000),
Tri-State (Oct. 2001).
Need Anything? (from Feb. 2002; I’m semi-retired now, so for the foreseeable future these notes will be reconstructed from sleep-deprived memories.)
Travel story, better lost than found: Signs.
Nothing much: more good and bad words,
general travelogue cleanup
(with some new bonus stories hidden throughout).
I can’t keep up! Here with the Wind,

Ne Pas Déranger.
- 2002-04-09: Updated failures.
- 2002-03-30: Started Lost Arts page.
- 2002-02-24: Some math corrections:
fixed the Fibonacci formula,
fixed the Lozi Attractor’s
aspect ratio (though not the Hénon Attractor’s),
and fixed the 5D paths
to avoid taking shortcuts.
