LEGO is an awesome toy, but no fun for your feet when you tread on it. This clever adaptation of IKEA's bargain LACK table creates a handy building surface and minimises mess.
As detailed by Adriana at IKEA Hackers, fixing a LEGO baseboard to the table is a good idea, but what I really like is the addition of hooks to hand buckets of LEGO as well. Hit the link for full construction details.
