Okay, so I figured that the Alethiometer program I posted a link to wouldn't work on a Chumby, as it's not in Flash. Since my last post, I've been working on a Flash version of it but, as I have never really programmed with Flash/Actionscript before (I've made an interactive lightsaber, but that was following a tutorial...), I am having some trouble getting the needle to work how it's supposed to. If anyone is willing to help me out, please reply here. I will of course give credit to anyone who contributes to the program.
