Create a graffiti-style version of the "NASA" logo while preserving the original shape and legibility of the logo. The graffiti should feature bold outlines, dynamic shapes. Keep all drips and spray effects contained within the boundaries of the logo itself. Limit the color palette to only 2 or 3 solid colors sampled directly from the original logo to maintain brand identity. Ensure the final result looks like a cohesive logo, not a wild wall tag. Use a white background and a square aspect ratio. --niji 6 --s 250 --raw
