Do you have a big bin of Legos from various sets that you’ve collected over the years? Now you can take that mess of random parts and turn them into other Lego sets. The website rebrickable will let you type in the Lego sets that you have and tell you what sets all those parts can turn into. It will also tell you which parts you will need to complete the sets. I tested the site with two castle sets that I have and the results were mostly other castle sets, which makes sense because of the parts. This may not be useful to all lego fans but it could be very useful for some.
