I owe U, U owe me, We owe the future

I stumbled over a new very pedagogic interactive graphic of world debt, divided on households, government, financial and non financial companies, from the Economist and saw that usdebtclock.org had been updated to include real time numbers on external and public debt for a couple of countries.

They can be found here:

If you are not 100 % sure about these terms here are two good definitions and explanations from wikipedia:

External debt
Internal debt
