When I hear "snapping software like Lego bricks" my mind immediately goes to the Spring Framework, which must be one of the largest, most-used, and most complete (modern) attempts at this paradigm. I haven't used it for anything large, but I would say it does not deliver on that promise. I'm curious to hear from those who have worked on large, sophisticated, Spring Framework apps - does it really feel like snapping pieces together?
