This looks like a really fun open source project. Particularly thrilled
to have another way to generate ascii fonts or even better, it seems to
have a font editor to make your own ascii font.  A lot of the fonts are
pretty cheesy, but some of the 3d fonts are quite lovely.  Do you have
any animations to show us?  I couldn't get the animator to output
correctly.

yes, the ascii fonts are called 'figlets' and you can collect them on the web i 
believe
but i haven't tried this yet. making them would be much better i'm sure.
it would be cool if there were a font import tool for the figlets.


my piece on Chladni plates was a gif animation using jave.
the interface is a little clunky and non-intuitive. its been awhile since
i tried any, but i know it works.. you build to the desired length by adding 
frames
in the animator applet (you can copy the same frame over and over
and then manipulate it by jumping through the list from the dropmenu in the 
main window.
you shouldnt need to fiddle with the anim. applet again once youve built the 
frames..)
what i did for the chladni piece was to do 3 different
'coding' styles for each import 'grouping'.. i imported a c.plate changing the 
'coding' or
visual algo to make 3 different copy-frames of the same image, this gave the 
same pattern
a kind of 'moving stillness' and let the progression move at a more readable 
pace..
if you keep fiddling with it you'll figure it out..maybe! i can't remember but 
maybe
I had to do some tricky business with photoshop at the end to get it perfect. 
crap,
i can't recall.  i'll try to make one when i can and see what issues i have. 
fbf animation is always a little tedious to
me.
but i really thought the plates needed to move as the original experiment is 
based upon the movement
of sand upon a drum-head or resonator. blahblah anywhoo--->

Here's the original posts:

ASCII permutations of a short range of square Chladni plates.

here are some the original drawings Chladni did.

The basic experiment that is given the name "Chladni" consists of a plate or 
drum of some shape, possibly constrained at
the edges or at a point in the center, and forced to vibrate historically with 
a violin bow or more recently with a
speaker. A fine sand or powder is sprinkled on the surface and it is allowed to 
settle. It will do so at those parts of
the surface that are not vibrating, namely at the nodes of vibration.

The equation for the zeros of the standing wave on a square Chladni plate (side 
length L) constrained at the center is
given by the following.

cos(n pi x / L) cos(m pi y / L) - cos(m pi x / L) cos(n pi y / L) = 0
where n and m are integers. The Chladni patterns for n,m between 1 and 5 are 
shown in the ASCII animation.



Some Further background:

Ernest Florens Friedrich Chladni (1756 - 1827) performed many experiments to 
study the nodes of vibration of circular
and square plates, generally fixed in the center and driven with a violin bow. 
The modes of vibration were identified by
scattering salt or sand on the plate, these small particles end up in the 
places of zero vibration. Ernst Chladni first
demonstrated this at the French Academy of Science in 1808, it caused such 
interest that the Emperor offered a kilogram
of gold to the first person who could explain the patterns.

Chladni's influence extended to Johann Wilhelm Ritter, who in 1801 discovered 
ultraviolet rays
and in 1803 the polarization of electrodes in batteries. "It would be beautiful 
if what became
externally clear here were also exactly what the sound pattern is for us 
inwardly: a light pattern,
fire-writing," Ritter observed of Chladni's figures. "Every sound would then 
have its own letter
directly to hand." Ritter's own avowed aim was "to rediscover, or else to find 
the primeval
or natural script by means of electricity." Ritter was a major figure for 
Walter Benjamin
(disclosing to him "what romantic esotericism is all about"), prompting the 
speculation
that "written language grows out of music and not directly from the sounds of 
the spoken
word." Much under the sway of the Kabbalah and the Pythagorean doctrine of 
cosmic
harmony as transmitted through Hermetic lore, Benjamin envisions the word as a 
trace
of primal pulsation (not unlike the hieroglyphic suggestiveness of the Chladni 
figures.):

One is tempted to say that the very fact that [words] still have a meaning in 
their isolation
lends a threatening quality to this remnant of meaning they have kept. In this 
way language
is broken up so as to acquire a changed and intensified meaning in its 
fragments. With the
baroque the place of the capital letter was established in German orthography. 
It is not
only the aspiration to pomp, but at the same time the disjunctive, atomizing 
principle of the
allegorical approach which is asserted here. In its individual parts fragmented 
language has
ceased merely to serve the process of communication, and as a new-born object 
acquires
a dignity equal to that of gods, rivers, virtues and similar natural forms 
which fuse into the
allegorical.

In 1928 Benjamin's friend Theodor Adorno, adressing the musical implications of 
mechanical
piano scrolls, recalled Ritter's reference to Chladni's figures as "the script-like 
Ur-images of sound,"
adding that "recent technological development has, in any case, continued what 
was begun there:
the possibility of inscribing music without it ever having sounded has 
simultaneously reified it
in an ever more inhuman manner and also brought it mysteriously closer to the 
character of
writing and language."
