Comet 17/P Holmes is in best position for observations and a lovely view in binoculars and small telescopes. So inspired, I have put together a comet monitor which performs various calculations and graphic transformations thereof. The online updateable database includes over 200 comets, all of which can be converted to a GoogleSky overlay. Help is embedded in the program. Written, of course, in Basic4ppc.
