Parametric facade apertures on swooping surfaces are out, parametric emoticons are in. A quick experiment using the image sampler node in Grasshopper to parametrically control the relative ecstatic to furious expression of an emoticon. A sampled pure white pixel on the original background image produces full-mouthed, googly-eyed happiness, while a sampled black pixel will unleash furrowed-brow, pursed-mouth rage. Grayscale pixels produce the range of conflicted emotions in between. Grasshopper definition can be downloaded here, works with any image, but simpler images with fewer colors tend to produce more legible results.
