Done with a ballpoint pen and a highlighter marker this pre-viz was alot of fun. The animation had to do with kidney function and filtration. Using several different histology sites as reference, I really enjoyed playing with the picture plane, its framing and an arching camera motion revealing in the inner workings of the glomerulus. Really ended up liking the resulting pallet of drawn frames with the oversaturated day glow yellow and rich blue of the pen.
