processing. twitter + madlib
since moving to munich, my time has been spent filling out paperwork, looking for work, looking for apartments, and realizing how bad my german has become. this of course leaves me no time to actually do stuff. i have some other stuff in the works that i started in san francisco, but it's not ready by any means yet.that said, to close the gap and make myself not feel so lazy. here's a project i completed back in april of this year. i had started it much earlier, but i made myself complete it in time for a presentation i gave when i worked at landor.
basically it's a mashup (is that right?) of twitter + madlibs + color tracking. i used blue light because we had a box full of lovely brinks LED-keychains in the office.
my idea was to create a modular and interact-able mad lib. using space as a medium of control, whenever a person moves in the room the story changes. on top of that using twitter as a means to augment the list of words used.
using a series of hashtags on twitter to represent the word types required for the story, desired words need to be added one hash tag at a time. if you mess up, there isn't a way to correct it, as even deleted entries remain in twitter's search cache for a while.
#s_noun (singular noun)
#p_noun (plural noun)
#s_adj (singular adjective)
#n_number (number)
#s_lat (superlative)
#s_verb (singular verb)
#p_verb (plural verb)
#pt_verb (past-tense verb)
#p_name (proper name)
#p_place (place)
at first i tried to access the twitter api using processing's built in xml library, but that didn't go so well so in the end i used the twitter4j library. however, it's reference/api was cumbersome for me to understand so i ended up writing my own class to handle accessing the data. it's a little sloppy and maybe there's an easier way. make sure you add the twitter4j .jar to your sketch

g = toggle sensor grid
m = toggle mouse or LED control
t = manually query twitter for updates
v = toggle video display (for debugging of LED control)
still to do:
- mirror coordinates (webcam)
and maybe one day:
- changing of LED detection color dynamically
