Thanks. All all Java, with the Processing API.

Sure. Well, for the font, I used the geomerative library [ ricardmarxer.com/processing/geomerative/documentation/ ]. I created an RFont object with the FreeSans font. Then I created a polygon group object (from the RGroup class) from the RFont object and I moved them out to uniform lengths with the RCommand class:

RCommand.setSegmentator(RCommand.UNIFORMLENGTH);

If you don't do this, they will be unevenly spaced. All I needed were those points. I then created invisible particles of a large mass at each one of those points. The colored particles are very light and are randomly scattered and assigned (but with an even distribution) to be attracted to these massive invisible particles. They are rendered with flight404's particle texture [ flight404.com/blog/?p=115 ] and OpenGL's additive blending settings [ processingblogs.org/2007/03/31/mini-tutorial-additive-blending/ ]. Once the simulation starts, they just naturally fall and oscillate into place. To learn more about particles, vectors, and attraction, I highly suggest reading this [ shiffman.net/teaching/nature/ ] by Daniel Shiffman. Don't stop learning.
