Ah well, I have a knack for losing lego pieces *sigh*
Lego (and other similar building block toys, such as Meccano) are probably the best ways to express your technical creativity. I believe these days, Lego Mindstorms are the "in" thing.
Remember, your learning experience also happens at home. You can't blame school for diminishing your creativity, when you have ample opportunity at home
Thus, your family plays a big factor during your upbringing.
