Joel modeled the tricycle with Blender 2.5 and then rendered it in Luxrender 0.7.1 "I let it run overnight, it ended up running for about 16 hours and got up to 15k S/px at a resolution of 1000x750. I used a single hemi/environment lamp with an HDRI for lighting. " He added some post processing with Photoshop. In addition to the render Joel created a completely working 3D printed model at Shapeways. You can view the video below.
