Art that expresses local and regional traditions are very popular at art festival. Art that is made from materials specific to the region or that tell a story about the region would fit into this category.
Many art festivals are also cultural events that showcase the artistic traditions of particular ethnicities. African, Mexican or Asian art are popular themes.
Small sculptures made from single or multiple media are increasingly popular at art festivals. Pieces made from scrap metal or recycled materials would fit here.
Live demonstrations and performance art--including portrait booths, interpretive dance and craft workships--are also gaining popularity.
Art festivals have also gone high-tech. Digitally rendered artwork, virtual art shows and computerized, interactive sculpture are increasingly available at art festivals.
