The flow of urban arts festivals has reached fever pitch. All around the world, artists are descending on towns to add their flavor to the local landscape. In Tudela de Navarra, Spain, the Avant-Garde Urbano Festival hosted the likes of C215, Escif, and JCHM IX. 

Amid the group, RIPO caught our eye. His mural, "Surreal But So Real," pushes the boundaries of typical text-based work and stretches the typography in fascinating fashion. He's taken over a full wall...with each letter requiring a bit of thought to work out. Smart stuff.
