Make new Lego sets from other sets
If you love both Harry Potter and Lego, there’s a good chance you own a Harry Potter Lego building set. Likewise Star Wars. Or maybe you’re just a Lego fan who’s crazy about building cars and houses and other worlds and such. But what do you build after you’ve built a Lego Death Star from the Death Star kit? Rebrickable lets you plug in the kit numbers you already have and tells you which other kits you unofficially have by combining the others.
Excellent idea, but it’s not quite as cool as it could be since it’s probably still works best with the special branded Lego kits. We plugged in a basic brick kit, the Burrow from Harry Potter and the Millennium Falcon from Star Wars. Rebrickable told us we then had all the parts that make up some random basic brick kits as well as all the bricks to make the South African flag.
