First off if any of the GiCentre library contributors are out there: thank you, this library is friking brilliant. What I'm trying to do is this. I have an interactive art piece that processes a lot of live data from the web and as a part of my piece I would like to run a data visualization slideshow without human interaction. I and several friends are working on some stand alone sketches based on a data template I have provided. I would like to use the gicentre multi-sketch library slideshow to add all of these child sketches to single parent slideshow sketch. My problem is I would like this visualization slideshow to not require any user interface. I would like to fade from one sketch to another (either in a fixed sequence or more preferably at random) based on a timer. I have spend a good deal of time playing with the Slideshow example but because there is no draw loop in that sample I am not sure how to apply the library for my desired outcome. I am also a bit afraid of hacking something I don't really understand for fear of introducing instability into my display. Anyone have any ideas how I can do this?

I am playing with some of the example code from the progaming handbook and noticed something strange someone may be able to help with. I am seeing differing behavour in a sketch when I use the hex representaion of a color rather than the rgb representation. This is based of of example  37-04 in the typogrophy II section.

This code works fine:

PFont font;
int opacity = 0;
int direction = 1;

void setup() {
  size(100, 100);
  font = loadFont("EurekaSmallCaps-36.vlw");
  textFont(font);
}
