Oh my god, yes this is it! and yes it was in Flash. I had completely forgotten about the name but clearly remembered the site. Thanks for bringing it back.

EDIT: I tried to run the SWF file on Ruffle but there is no data. I can imagine that the SWF contacted some backend server to load data which is no longer available.

Any idea if this sort of data is still available?

I’m kinda sad that theyrule didn’t live on and become an institution, honestly
