Are you kidding! Legos are used by engeiners and 3d modeles to make up sketches of deseing and mechanism prototype. The best car in the world was done in lego first. then it was drawn on paper and later it became reality. Legos are tools of creativity! They should have a class at school at each Grade. Creativity and curiosity seems to be completly absent now days in school.
You can use 3d modeling rather then legos but still legos are more fun. You practice your sight for finding small pieces in a cluster F/"$"/$ of rainbow color pieces. You practice you manual Dexterity! and ou fuel Creativity! "Warning addictive feeling"
Um, ya kinda! Well, not so sure cause if he plays with them all the time like my brother then yes, but every once in a while should be fine! Dont ya think so! I mean, I still think hello kitty is SUPA cute! ;)
