Some might say LEGOs are TOO wonderful!
My son loves them and has developed great manual dexterity by building many of them. From Fire Engines to Trains to dinosaurs, he's been having a blast. Now it's hard to store them without eating-up lots of cabinet and bookshelf space...
So one night while watching How it's Made on TV, I started dinking-around, drawing an interlocking set of adjustable shelves using Corel Draw 5 (version 15 when you save the file).
I built these out of cheap 1/4" MDF. Fortunately Legos do not weigh a whole bunch, so I felt comfortable using 1/4" MDF.
They feature Earthquake Lips, which help keep the vehicles from rolling onto the floor...
Luckily, I've got access to a 60-watt laser cutter/engraver as a member of TechShop in San Jose, California. Check 'em out at http://techshop.ws
I made a couple of sets of shelves that can hold the lightweight LEGOs. This main photo shows only the bottom and middle shelf backboards - putting the top shelf backboard puts the shelves out of reach - too high for my son. All the shelves shown in the picture cost a total of maybe $20.
Step 1: Get the MDF
MDF: Medium Density Fiberboard
**** NOTE! Home Depot is no longer my supplier for MDF. ***

I pay about $5.25 per 2' by 4' sheet of 1/4" MDF at my local big home improvement store. Home Depot works well for this stuff. Last time I measured with a micrometer, the actual thickness of the Home Depot 1/4" MDF was .236 inches.
MDF quality varies. It's worth confirming you've got a dimension that will work well with 1/4" mortises and tenons. Do some test-burning on the laser cutter/engraver before buying lots of MDF and expecting the parts to interlock well.
Cut the MDF to 24" x 18" pieces or have them cut for you at the home improvement store.
The machine you use to make the cuts will need to accept a 24" by 18" piece of MDF.
