OMG! I just found this article on the internet and was simultaneously thrilled and shocked. This guy must have OCD (yeah, takes one to know one) or no children. I no longer have any Legos in my house, but I so could have done this when I did. However, I would NEVER, EVER let the kids play with them ever again! Not if I put that much effort into organizing them.
I do, however, love plastic ziploc bags for organizing toys. I can separate toys into baggies like no one else. Then all you have to do to keep them neat is to place the baggies into neat little stackable bins. The hardest part about it all is that the children don't quite seem to "get" the concept of keeping their toys nice and neatly organized. Especially that Katie. She keeps unalphabetizing her books, and I can't tell you how many times I've put her tea set back onto the tray the way it's supposed to be.
