Collapsing Grid 9

A gradient-based shader effect displaying a smooth tonal transition from black at the bottom to white at the top, rendered through a pixelated circular dot pattern. The composition features approximately 16x8 grid of rounded circles with varying opacity levels, creating a halftone-like appearance. The circles transition from solid black on the left and bottom edges, through medium gray tones in the middle sections, to pure white in the upper-right quadrant. The pixelation scale of 18 with 0.03 gap spacing creates distinct circular cells with rounded corners (roundness mapped from 0.13 to 1.0). The overall effect produces a smooth luminosity gradient despite the discrete pixel structure, with a dark background (#121212) providing contrast. The swirl component beneath adds subtle color blending between white and black in oklab color space, creating smooth tonal transitions. The effect has a technical, data-visualization quality with precise geometric spacing and mathematical gradient progression.
