Wakacyjny Konkurs WMBF ("Holiday Contest WMBF") was an annual brickfilming competition held officially by the Polish-language brickfilming website WMBF until 2015. The start and end dates were the same each year during the summer months, beginning on the 1st of July with a deadline of the 1st of September. A different theme was used each year and mod elements were required to be in each shot of the entries.
