I have waxed poetic about my love of legos before (see here, here, here, and here), but this amazing boardroom table, created by the firm abgc architects for an advertising agency in Dublin, has my mind spinning. And with a little bit of planning (and a whole lot of legos!) I can totally imagine making a kick-butt dining table or desk for a kid's room. Definitely more practical than this big lego project!
