Is there anything like a 'recipe generator' for LEGO models? For me, most of the fun of LEGO toys, is building new things from the instructions. Rebuilding things can be fun, but if I know I have certain bricks (or even sets), is there somewhere to cross-reference these with the content of other constructions/sets (official or otherwise)?
Yes there is! Rebrickable.com is dedicated entirely to doing so. You can save time and import your LEGO collection from Brickset.com (If you have an account). The site will then search for other sets and MOCs you can build from the bricks you have in your collection.
