Show HN: CuriositY

This is interesting. However, I seem to have hit a roadblock at level 6 (layer). I tried changing the z-index (thinking it might reveal something, because - layers), but in vain. Scanned through the HTML and css. Nothing, still. Hints?

I'm stuck at the shape.csv. I've tried converting it to a KML, but I can't seem to get it to display on anything.

Actually quite interesting.. But frustrating as well ;)
