Lego is awesome, that CAD software has been out for ages and free to download, its been advertised in the lego club fan mail for yonks now (I'm 22, a member and still receiving it!

), brilliant as you can build stuff and then print a sheet off all the components used. Go to your lego outlet pick up there dispenser pots and got to the parts wall, pick out the stuff and fill up your pot(s).
Shame the Lego company is a pain in the ass to deal with as not all parts are available in the shop, they refuse to let you order in bulk, even with no discount... really a kill joy for enthusiasts.
