Yep, it's pretty simple with Python, I do it as well using the json API (left screen). C is another matter, though, several more levels of difficulty. And, since the bargraph is constantly being updated, not sure it's feasible to display the art on the right-hand device, as it would need to be updated about 30 times/second or be obliterated by the bars. Would need to be displayed without the bargraph, I think, using a touch to switch between modes...
