This "Everything Table" was created by Craftser user leighi123 (and the winner of the Handmade Holiday Gifts for Kids 2 challenge) that she crafted for her 4 year old son for Christmas using an old shoe rack, wood and felt and integrating a few other items and toys.
Not only could this be made at a minimal cost, it also takes up minimal space (see last picture).
Moon and Earth
Under the Sea
All of this stores in bins and baskets below the table so it takes up minimal space
Wizard of Oz
