Viewing javascript source maps visually

Question

I remember finding a source map viewer somewhere one time, which showed you the source and the source-map side by side (i think also with the compiled code), and let you scroll your mouse around to see different parts of the source map.

I can't for the life of me find it now, but I really want to use it to verify the integrity of my source map (can't tell if bug in the map or in chrome).

Anyone know what I'm talking about?

Oh, YES I found it! From the guy who gave us webpack:
