There is a nice one included in pdmtl called gems.win.feedback

Thanks. I know that it is inherent in the system, but is there a way
to control the "fuzziness" of each iteration, so that the image
loses its alpha value but retains the sharpness of it's outlines?

which objects could be used to make this framebuffer?
gemframebuffer.
here is the patch jack send recently on the list.

this was the old way to do (but still working fine).
i think it can be faster to render in a framebuffer, and use this
framebuffer as a texture to draw in a 2nd framebuffer.
and drawing back to the 1st.
etc.
there are also some example in the glsl section.
jack also send a simple exemple somwhere recently.

The other night I watched a very nice lecture from Paul
Prudence (dataisnature.com). He uses VVVV to make audio-
responsive video feedback, where a single shape (a square) is
recursively displayed, causing very complex structures to
arise. The relevant parts of the lecture are here:
http://www.vimeo.com/2930699
http://www.vimeo.com/3003040
although I would encourage people to go through the whole
thing (11 parts on Vimeo) if they have time + interest.
I'd at a loss to think of how something similar, i.e. the
recursive feedback, could be done in GEM or PDP. Any
suggestions?
best!

If nature has made any one thing less susceptible than all others of
exclusive property, it is the action of the thinking power called an
idea, which an individual may exclusively possess as long as he keeps
it to himself; but the moment it is divulged, it forces itself into
the possession of everyone, and the receiver cannot dispossess himself
of it. - Thomas Jefferson
