I made this in 2009, in Maya, a 3D modeling and animating program. I Modeled it directly from the California Hell Rider's Wall of Death. I Met the crew at the Rhinebeck Swapmeet. Super cool people, they allowed me to go inside the wall for reference photos. At the following Rhinebeck meet in 2010 I gave them prints of the final renders. They were pretty stoked about it.
