kdzic emailed this toy storage idea. not really a hack but useful if you're looking for new ways to organise your child's collection.
take the $79.99 expedit bookcase and turn it on its side. pick up some industrial parts sorting bins from usplastic.com (items 53114 and 53115) and slot them into the shelves. 20 minutes work and no more toys sprawled out on the living room floor.
and the expedit is turning out to be highly hackable.
