WARNING: Some web admins deem a scan of this nature to be an attack. Traceroute scans and the like are fine but if you are scanning their ports and services, they'll probably do something equally silly, like scan you back, or add you to their firewall block lists. You can also crash webservers if they are not configured propperly, so please, don't be that guy!

This shows the "hops" your computer takes to get to a specified website or web-address. You can visualize CDN's, look at cool routing anomalies within your ISP or even find out who's really hosing that web server.
If you're into infosec or are interested in your own opsec you can run this on your systems and see what happens.
Let's see what happens when you run a traceroute to google.com through your ISP.
