Simplicity

2011-02-03_22

Today I made not a single purchase and all of my food from home
without the benefit of leftovers.  This is something I value and
encourage but rarely accomplish!  Three simple dishes and not a single penny spent on
/anything/ all day :).

Breakfast simply rolled oats, plain yogurt, and a bit of maple syrup
with a hearty stove top espresso.

Lunch was garlic, zucchini, mustard greens, green onion, parsley, and
a few eggs on local corn tortillas (with cock sauce).

Dinner (pictured) included green beans sauteed with garlic and shallot
alongside radiatori tricolori pasta with green onion, parsley, and tillamook cheddar
:).

Origami 1

Six 60 degree units for a modular tetrahedra piece!!  Id like to
combine this idea with the peneose idea from yesterday.  This took
about an hour, bigger pieces will take multiple thingadays... perhaps.
Trippy :p...  2 of 28.

Penrose 1

Hi everybody :). I'm hoping to play with some origami this month as
well, and it'd be sweet if I could figure the angles out to build some
in penrose shapes.

From en:wiki:

A Penrose tiling is a non-periodic tiling generated by an aperiodic
set of prototiles named after Sir Roger Penrose, who investigated
these sets in the 1970s. Because all tilings obtained with the Penrose
tiles are non-periodic, Penrose tiles are considered aperiodic tiles.
A Penrose tiling may be constructed so as to exhibit both reflection
symmetry and fivefold rotational symmetry, as in the diagram at the
right.

A Penrose tiling has many remarkable properties, most notably:
It is non-periodic, which means that it lacks any translational
symmetry. More informally, a shifted copy will never match the
original.
It is self-similar, so the same patterns occur at larger and larger
scales. Thus, the tiling can be obtained through "inflation" (or
"deflation") and any finite patch from the tiling occurs infinitely
many times.
It is a quasicrystal: implemented as a physical structure a Penrose
tiling will produce Bragg diffraction and its diffractogram reveals
both the fivefold symmetry and the underlying long range order.

Various methods to construct Penrose tilings have been discovered,
including matching rules, substitutions, cut and project schemes and
coverings.

text says : "not possible to create tilings using only the matching
rules." , so I can't just start with a shape and "build" one of these
patterns without expecting it to eventually break and become periodic.
I didn't fully realize this before tonight!... more on this as I play
with it :).
