Whoops, my bad.  I just assumed it was basically the same.  I guess it's still onion routed in the sense each layer is encrypted for the next hop? I'll have to look into how tor works at some point.

[Education] Onion Routing on the Lightning Network

That's a pretty good summary but worth noting that it describes specifically Sphinx onion routing (the onion routing in Tor is not the same). See [the paper](http://www.cypherpunks.ca/~iang/pubs/Sphinx_Oakland09.pdf).

For people who want to understand it in a bit more detail, there is a great writeup with diagrams in [Mastering the Lightning Network](https://github.com/lnbook/lnbook/blob/develop/10_onion_routing.asciidoc)
