The Roswell Pentimento manifests as a disc of layered glass or ceramic, approximately the size of a disc golf driver, with visible strata of color bleeding through the surface like watercolor on wet paper. Each layer glows with the chromatic signature of its previous holder - deep blues for defensive players, golden streaks for champions, gray smudges for those who faded. The edges shimmer with the residual energy of transitions past. The surface temperature varies between historical and current layers, and subtle harmonic resonance emanates from accumulated competitive moments.

The Roswell Pentimento serves as the cosmic archive of competitive history - when a player takes a bag tag, they inherit not just a number but the visible ghost-strata of all previous holders, and their own performance will similarly bleed through for future competitors. This creates a continuous chromatic record where every throw adds permanent pigment to the eternal artwork.
