Sure - it only started to collect data about 10 hours ago but that's certainly the plan.. though I've realized it's already useful for me to catch up with HN while I was asleep.

Regarding animation, thanks for the idea. I'm really just a JavaScript "dabbler" but I'll have a think about how it could be done. Rather than just rendering a JSON file into HTML it seems I'd need to start storing the data as it comes in and perform manipulations as necessary. This might be a bit too much for me for a quick project but I'm open sourcing the code so it could happen.
