Question: Can you list the names of the festivals that had two or more nominations for artwork?
SQL: SELECT T3.Festival_Name FROM nomination AS T1 JOIN artwork AS T2 ON T1.Artwork_ID   =   T2.Artwork_ID JOIN festival_detail AS T3 ON T1.Festival_ID   =   T3.Festival_ID GROUP BY T1.Festival_ID HAVING COUNT ( * )    > =    2
