hello processing geniuses,
im working on a logo that involves a harmonious group of particles that revolves around a letterform; i need some help with the particles. so heres the gist of it: each particle is generated by a tweet that consist of six different keywords: air and space, creative court, ecosystems, innovation lab, rain forest, and world of life. each keyword is represented by different colored particles, as shown below:
air and space tweet : dark purple particle
creative court tweet: orange particle
eco systems tweet
: blue
particle
innovation lab tweet
: pink
particle
rain forest tweet
: green
particle
world of life tweet
: red
particle
the differentiation of the colors, once the particles are generated by twitter feeds, allow the user to see just about which topic is most popular; if
green particles seem to populate the space more so than other colors, they get a clearer sense that the topic of
rain forests is most talked about.
heres my question: for my set of codes, i was wondering if you guys can help me write how i can make this function possible.
also, i was wondering if you guys can help me how to tie in the twitter feed function to my code.
for now, the particles can be generated by clicking the screen.
for the processing code,
i have set two tabs to reduce the clustering of codes.
if you prefer the actual code, you can download it here:

note: the gradient function is very important, so the twitter function is powered by twitter4j.
thanks! much appreciated
