MOC

MOC = "My Own Creation"  Or, in this case, "Your Own Creation."

A MOC is anything, great or small, built by us, the AFOLs and not Lego Group professional designers.

MOCs are the key feature of BrickFair.  Hundreds of AFOLs get together and show off their MOCs, share ideas, and envy the ingenuity of others.

When you register for the full BrickFair weekend, you are invited to bring your favorite MOC to show off.
