July rotations

Been trying to explore Blender's features in small 3D sketches. Both of these use custom fresnel shaders for colour shift. The heart uses a stack of modifiers, including displace (with a perlin texture) and array, distributed along a curve and mirrored. The pigeon uses grease pencil which I still haven't found the magic of yet. I've seen it used to beautiful aesthetic effect, and I need to work some more with it to find that for myself.
