How was "ten thousand cents" implemented?

Question

How was ten thousand cents implemented? I am particularly interested in the implementation of the interface that accepted the drawings from the user? Are there libraries available that facilitate this?

Answer 1

One key ingredient seems to be the Processing library -- this is probably what you are looking for. From their FAQ:

How did you put everything together?

We used a few different tools to create everything. The interfaces were done with Flash, the movies with After Affects, most everything else was done with Processing, and of course, the eyes and hands of thousands of workers online.
