Nauti the Nautilus - This took roughly 7 hours start to finish. I got rained on for about an hour half way through painting it so really 6 hours is more acurate. It is located at Castle Hill Graffiti Park (also called Hope Outdoor Gallery/Baylor Street Art Wall) in Austin, TX USA. Total size is roughly 20ft long by 9 ft tall. Materials used: Acrylic paint, house paint, brushes, rollers, and Sharpie Markers.
