Create a vivid image of Elon Musk deep in thought, captured in a Neo-Pop Art style, with his facial expression conveying contemplation of groundbreaking ideas. Surround him with symbols of his ventures: Tesla, SpaceX, Neuralink, and the Boring Company. Use a vibrant color palette of bright reds, blues, yellows, and greens, with bold black outlines characteristic of Neo-Pop Art. Incorporate collage elements, mixing photographs, text, and graphics to create a striking composition that embodies the dynamic energy of Musk's entrepreneurial vision. Emphasize his central role by arranging symbols and elements to radiate outward from him, slightly altering elements for creative effect.
