Step 1: put the iPod on shuffle.
Step 2: dump out all the giant plastic boxes of Lego onto the miscellanious bricks already on the floor. This adds up to about half your collection.
Step 3: sort it all out into giant ziploc bags of black, dk grey, light grey, brown, white, etc.
Hooray! It's been only five hours and already I have several large bags of Lego to organize further, as well as excruciating back pain. And I'm not even half way done.
It's going to be quite a day.
