Hello All,
an experiment using spirograph curves mapped to waveshaping 
instruments (1 instrument every 3 equation/curves for 6 coefficients,
1 for x position and 1 for y).
Waveshaper by chebyshevpoly.

Thanks,
ciao,
francesco.

Very nice, can I ask how you generated the graphics?

Sure.
And it's overcomplicated because my poor programming skills.
It's a Lua script that use IUP graphics library. It save 1 image/frame with
a timer
set circa every 40 ms (25 fps). There are two processes 1 for entire curve
and 1
only for tracking points. At the same time Lua calls Csound to perform the
csd
in realtime using channels and the wave file is by fout opcode.
Then using avconv program the script render two films from jpeg images and
then i make a final mixing with those two films and audio.
But then again i had taken 5 films and mixed together for final video.
That is because after 3 minutes spirograph sound tend to be boring!
Like i said overcomplicated.

Thanks for listening.
ciao,
francesco.

Thanks for the info. That sounds like quite a process, but when it
turns out this well it's all worth while. It reminds me a little of
Norman McLaren, more so in its simplicity than anything else. And by
simplicity I'm referring to the generated graphics rather than the
process behind it!

Thanks All.

To Mr. Gogins:
if You mean the Lua interpreter i use LuaJIT, or do You mean 
somethings different?
Of course one inspiration is Your work! For example the use of Strange
Attractors, 
or IFS, or the tutorial on algorithmic composition.
And thanks for let me know about Lua. Some years ago i was starting study a
little bit
programming and i read about Lua in a Your post. I began with Python but Lua
captures
my attention and now i use it for almost all my work and how it's fast.
True that my work is really limited to simple tasks, but i only do that for
my pleasure.

ciao,
francesco.
