I down loaded the code and took a quick look at the included files and the .pde file. The microSD card setup is interesting (but I don't have one to experiment with yet). I noticed the use of .js files. A while back (before I had an arduino) I tinkered with a slider.js file to make a sliding servo controller page (below) for an apache server setup. The same type of setup might be of interest with controlling lights and similar with an arduino.
