Yes I would agree that is half the fun, unfortunately with a 3 year old running about the place during the day (and half the night atm) my missus's idea it would be something I can just do in the coffee table now and then while she does her crappy crafty crap may be a bit of a pipe dream! The spare room and its nice desk is beckoning!
@freddymercurystwin there are multiple ways of doing it. But the most common would be to do as you say and tip it all out. Half the fun is to hunt for bricks. Excellent set BTW. I'm really jealous...
