Acknowledgements

The development of this project could not be possible without the support of many people. I want to express my gratitude to:

Victoria Sacco, for the project supervision and for believing always in me.
Albert Meroño, for the technical support at getting tweets and user images.
Julien Lagarde, author of the image that I used to create the header and other graphic materials.
Processing forum, for helping me with a lot of problems and accepting me as one more programmer.

I am especially grateful to:
my friends, for encouraging me all the time.
my partner for being always at my side and, very especially,
my family, for emotionally supporting me, although I live far from them.
