6 years ago Actually I got it going. New bit of sprites.py looks like this. (yes, it's modified destination sprite and yes theres lots of stuff I could drop from this)

More of a request than an issue, I would love if the standard fancytext object accepted a data_source. Also for that subway-arrival-time clock. I've finagled the code on my own to show the minutes for the arrival time - but the next step is actually showing the route destination rather than just the direction.
I'm not great with python - I know the data_source is looking for an integer, and I haven't been able to figure out how to make it just pass a plain string. If you have any time to implement this, I think that would be awesome. If not, I'll share my results if I'm able to eventually get it working. Seems simple enough - I'm just a novice at this.
